Democrats’ big win on Election Day, which saw them take control of both the House and Senate, has ramifications for the Cybersecurity and Infrastructure Security Agency, artificial intelligence, surveillance policy and much more.

Here’s what lawmakers and cybersecurity experts have to say about the short-term and long-term prospects on Capitol Hill.

Leadership plans ahead

Maggie Hassan, D-N.H. is in line to take the gavel on the Senate Homeland Security and Governmental Affairs Committee, with Sen. Gary Peters, Mich., retiring.

“Our government’s number one job is to keep people safe, and the Senate Homeland Security and Governmental Affairs Committee must work to ensure that our country remains safe, secure and free from all kinds of threats,” Hassan said in a statement to CyberScoop. “That work involves protecting against terrorism and fentanyl trafficking, but it also includes guarding against emerging threats like artificial intelligence security risks and strengthening our cybersecurity.”

“The Trump-Vance administration has undermined our security on these fronts, including by diverting resources away from combatting fentanyl trafficking and gutting CISA,” she continued. “We need to reverse these cuts, confront these challenges and put public safety first.”

Rep. Bennie Thompson, D-Miss., is poised to return once again as chair of the House Homeland Security Committee, said Democrats are taking over at a “pivotal time for CISA,” with it looking to add staff after cutting back by nearly one-third.

“First and foremost, we will aim to work with CISA to expedite its critical re-staffing effort and to ensure it has the expertise necessary to support stakeholders as they defend against the scale and velocity of AI-enabled cyber-attacks,” he said in a statement to CyberScoop. “Advances in AI can help defenders, but it will also accelerate the consequences of deferred investments in security and CISA must be well-positioned to help critical infrastructure owners and operators rapidly improve their cybersecurity posture.”

“We will prioritize getting resources straight into the hands for defenders — by extending the State and Local Cybersecurity Grant Program and improving support of under-resourced sectors, especially water,” he continued. “We will work to ensure CISA re-establishes its cross-sector coordination capacity, which was diminished when the Trump administration- terminated CIPAC, by making sure the Anchor-CI is eventually up and running and meets the needs of stakeholders. Finally, we will make sure CISA is well-positioned to support the secure development and deployment of AI.”

What happens in the lame-duck session

Before the GOP relinquishes control of the House and Senate to Democrats, though, there’s a lame-duck session ahead. 

Long-term renewal of the Cybersecurity Information Sharing Act of 2015 (CISA 2015) is a bipartisan and industry priority, with it set to expire Dec. 11. Current Senate Homeland Security and Governmental Affairs Chairman Rand Paul, R-Ky., has been the biggest obstacle to reauthorization, but he could get “rolled” by GOP leadership on an extension, said Michael Garcia, a former government cyber official and vice president of the cybersecurity practice at Monument Advocacy. Possible vehicles for CISA 2015 to hitch a ride include an omnibus funding bill or the annual defense policy bill.

The Department of Homeland Security, and its subagency CISA, are currently operating on a continuing resolution that’s also set to expire Dec. 11, where lawmakers could temporarily extend CISA 2015 if a long-term solution can’t be reached in the lame duck. Another continuing resolution before Dec. 11 in lieu of an omnibus spending bill is an option for the lame duck. Both a CR and omnibus spending bill would theoretically include DHS funding, although the agency’s funding has been made more difficult in the past by the presence of Immigration and Customs Enforcement within the department.

Republicans have talked about wanting to get the fiscal 2027 National Defense Authorization Act done in the lame duck. Besides the possibilities of CISA 2015 being included in the bill, Nicholas Leiserson, senior vice president for policy at the Institute for Security and Technology, said the Senate version of the legislation has a pair of very noteworthy cyber provisions: a “very broad” authorization for contractor-owned, contractor-operated offensive cyber operations, and a requirement that every artificial intelligence product sold to the Defense Department have an AI bill of materials.   

Additional leadership shuffle

While Paul is losing his gavel, he’s shown he can be a disruptive force on passing cybersecurity legislation through the Senate in the minority. That makes what he does next possibly determinative for cyber bills, Leiserson and Garcia said. “If he leaves HSGAC, let a thousand cyber bills flourish!” Garia quipped on social media. Paul could opt to become the top Republican on the Senate Health, Education, Labor and Pensions Committee instead of HSGAC.

Nebraska Sen. James Lankford would take over for Paul as top HSGAC Republican in that scenario, and an industry source said he’s viewed as a supporter of CISA 2015.

On Senate Intelligence, the panel’s leadership goes to a lawmaker who has placed a big emphasis on cybersecurity in his congressional career: Mark Warner, D-Va. 

On the House side, while Rep. Andrew Garbarino, R-N.Y., moves to the minority on the Homeland Security panel, he has proven willing to collaborate with Democrats on cybersecurity issues. Rep. Delia Ramirez, D-Ill., is poised to take the gavel of the panel’s cybersecurity subcommittee, and Rep. Vince Fong, R-of California looks set to become the subcommittee’s top Republican and has his own history of bipartisanship. Fong would replace current subcommittee chair Andy Ogles, the far-right Tennessee Republican who lost in the primaries.

One thing to watch in the House, Leiserson said, is how the House looks to tackle AI — through existing committees, a select committee or some other structure. Democrats haven’t put forward a unified front on AI guardrails yet.

With AI models uncovering as many vulnerabilities as they are, “highly capable frontier models are going to drive a lot of discussion” about AI and cybersecurity, said Craig Albright, the Business Software Alliance’s senior vice president for U.S. government relations.

Appropriations, oversight, legislation

If the NDAA or a CISA 2015 extension don’t pass in the lame duck, they’d be priorities in 2027, too.

“CISA 2015 has to happen, and if we can’t get it done, then we can’t move to the next thing,”  said Henry Young, BSA’s policy director. “Once we get it done, there’s an open question about which of these priorities that we’ve talked about gets to be number one. Is it post-quantum cryptography? Is it government IT modernization? Is it frontier AI cybersecurity systems? We don’t know that yet, and we can’t know until we pass this law.”

How damaged the agency CISA is by Trump administration’s budget cuts is something Democrats are expected to scrutinize closely. Another top budget issue is what to do with the expired State and Local Cybersecurity Grants Program housed at DHS, since even if it’s reauthorized, it will require appropriators taking steps to invest in it.

Democrats could take a look at a variety of other Trump administration changes at DHS and CISA, on topics like election security, the Cyber Safety Review Board, the Joint Cyber Defense Collaborative and more. 

More broadly, Leiserson said an area of Democratic cyber oversight is likely to be the Department of Government Efficiency that cut cyber personnel at agencies at and beyond CISA, and “particularly the integrity of systems that DOGE touched when they were given very high privileged access to federal systems.”

If the White House puts forward a permanent nominee for director of CISA, Democrats would be poised to vet that person. They also would have a say in who leads the Office of the National Cyber Director, should the incumbent, Sean Cairncross, depart.

So far, Democrats haven’t put forward a unified posture on expired surveillance authorities known as Section 702, although both Warner and incoming House Intelligence Chairman Jim Himes, D-Conn., have fought in the past for its renewal. The surveillance program is operating similarly still due to a court order, but that order only lasts through next spring.

A leak website was published Wednesday, showcasing internal data on more than 41,000 Department of Homeland Security employees and contractors after it was obtained by hackers who claimed to have breached an identity service used by the agency.  

The transparency nonprofit Distributed Denial of Secrets and the hacker maia arson crimew got the data from a hacktivist outfit known as the Department of Peace.

”The leak is extraordinary but deceptive in [its] simplicity as it identifies the officials responsible for overseeing covert and undercover operations, the government’s hunt for leakers and the failed BlueLeaks investigation — along with key personnel in DHS’s ever-escalating rendition and deportation programs,” said Emma Best, founder of DDoSecrets.

CyberScoop was able to verify numerous current Cybersecurity and Infrastructure Agency employees are listed in the data, along with some former leadership members who left the agency years ago.

The data goes back years, with various group names listed in the database making reference to COVID-19 planning and internal summits in 2023.

As of Thursday morning, the website hosting a searchable form of the data has been taken offline.

The hacktivists said the breach was a response to the promise of stepped-up operations from Immigrations and Customs Enforcement by DHS Secretary Markwayne Mullin.

”On July 17th, Markwayne Mullin said he was ’turning up the heat.’ This is what happens to ICE when you do that,” said a spokesperson for the Department of Peace.

The spokesperson said they obtained the database from an Okta single sign-on service used at DHS. Okta said it was aware of the report.

“Okta is secure, and we have no evidence our data or systems were compromised,” an Okta spokesperson said.

DHS did not immediately respond to a request for comment.

”This dataset is massive in terms of both size and impact,” said crimew, a Swiss hacker and journalist who has been indicted in the United States over past leaks and who created a search tool for the DHS data. “It provides an unprecedented look into the Department of Homeland Security’s organizational structure, highlighting which people do what work across multiple DHS agencies, including ICE.”

One researcher said the leak could prove valuable for Freedom of Information Act requests.

“Email addresses and phone numbers are indispensable tools for FOIA researchers, often making the difference between a vague records request that gets stonewalled and one that gets results,” Ryan Shapiro, executive director of Property of the People, said. “Given the Trump administration’s contempt for even basic transparency, the need for such tools is urgent.”

DHS has suffered notable breaches before, dating back to a 2014 breach that may have exposed the data of 390,000 then-current and former Homeland Security Department employees, job applicants and contractors. In 2018, DHS notified nearly 250,000 people of a breach at the department.

Earlier this year, Security firm GitGuardian said it discovered a public GitHub repository that exposed credentials for privileged AWS GovCloud accounts and internal CISA systems dating back to November 2025.

Hundreds of federal agencies should adopt an encryption tool to protect whistleblowers, veterans suffering from mental health crises and others from hackers who might target them when they reach out via agency websites, Sen. Ron Wyden said Monday.

The Oregon Democrat urged the Cybersecurity and Infrastructure Security Agency and Office of Management and Budget to take steps to adopt Encrypted Client Hello — a cybersecurity technology that protects the name of the website visited by a user — in a letter to the two agencies. His office identified at least 350 sites that don’t use its protections.

While almost all federal agency websites are encrypted, standard web encryption doesn’t secure some website names, Wyden said, using reportfraud.ftc.gov as an example.

“As data travels across the internet, hackers and foreign actors monitoring network connections can easily see these exposed website names,” he wrote. “This visibility could lead to malicious eavesdroppers identifying whistleblowers, profiling cleared federal personnel, tracking Americans seeking crisis support, and mapping interactions between agencies.”

Wyden wrote that Encrypted Client Hello (ECH) is especially effective with Content Delivery Networks (CDNs) that connect hundreds of thousands of websites to the internet. For websites delivered by a CDN, ECH makes it so anyone intercepting user web traffic can view the network delivering the content but not the specific site.

Agencies using CDN infrastructure without Encrypted Client Hello include an FBI tipline that supports ECH but doesn’t enable it and a Department of Veteran Affairs online suicide prevention hotline that isn’t protected by ECH because Amazon doesn’t support it, as well as agencies offering things like national security personnel services and whistleblower channels.

Because of the lack of ECH protection, foreign adversaries might be able to identify someone submitting crime tips to the FBI, Wyden warned.

Wyden made two recommendations to the leaders of CISA and the OMB.

“CISA should require that civilian federal agencies enable the protections of ECH across all public-facing websites and inter-agency web systems,” he said. “OMB, in coordination with the Office of the National Cyber Director and CISA, should establish support for ECH protections as a mandatory condition for commercial cloud and network vendors seeking federal contracts.”

CISA and OMB didn’t immediately respond to a request for comment on the letter, first reported by NextGov/FCW.

Wyden’s Monday missive is his most recent aimed at improving security technology at federal agencies, following on the heels of a letter in July first reported by CyberScoop that urged feds to get rid of older, insecure, public-facing VPNs.

A coalition of cyber firms and critical infrastructure operators on Tuesday spelled out its views on the tasks that the Cybersecurity and Infrastructure Security Agency should assign federal agencies to protect operational technology systems after this summer’s attacks on water utilities.

The Operational Technology Cybersecurity Coalition said a CISA binding operational directive (BOD) for OT should specify who is responsible for protecting these systems at each agency,, draw on existing federal guidelines and set minimum cybersecurity practices.

The coalition said the BOD would address a need to act based on CISA’s lack of visibility into the spectrum of OT devices in federal agencies, a lack of consistent across-the-board OT security policies and the severity of the consequences that an attack on federal OT could produce.

Just last month, the Government Accountability Office published a report which concluded that most federal civilian executive branch agencies (FCEBs) haven’t enacted Office of Management and Budget requirements released in 2023 for networked Internet of Things and OT devices.

Putting forward recommendations for a CISA directive has two goals, said Michael Garcia, policy director of the coalition.

“One, it does make sure that the government is taking its own medicine,” said Garcia, who until recently worked at the agency. “You should practice what you preach. … Second, it sends a very strong signal to the private sector that, ‘This is what we think is important: As an OT partner, owner or operator or critical infrastructure owner or operator, [this is what] you should ask other providers to do.’”

There are 8,000 General Services Administration-owned and -leased properties, many of which would have OT involved in everything from power supply to heating, ventilation and air conditioning systems. Some of those OT systems might be “trivial,” Garcia acknowledged, but the coalition paper notes that CISA “does not currently have a holistic view of the assets managed by the FCEB and the potential risks, such as connected programmable logic controllers, to which the government may be exposed.”

With OT falling into a “government gray zone” between chief information officers and facilities managers, CISA should tell agencies to formally designate an officer in charge of cybersecurity for OT, the coalition recommends.

The directive should examine past OT guidelines the National Security Agency issued to see if they should apply to federal civilian agencies, and align any requirements in the hypothetical BOD with cybersecurity performance goals that CISA first issued in 2022, according to the coalition.

The coalition doesn’t assert that such a BOD would have headed off the attacks this summer on the water sector, and is focused on federal OT, something where CISA has done some work.

“To be fair, CISA has incorporated OT security requirements into prior directives (such as BODs 23-01, 23-02, and 26-04) alongside a host of technical guidance,” the paper reads. “But as AI reduces the technical barriers to sophisticated cyber operations, enabling adversaries to identify weaknesses, accelerate reconnaissance, and move laterally through poorly segmented operational environments with greater speed and scale, it is time for an encompassing BOD solely focused on OT security.”

CISA didn’t respond to a request for comment Monday in advance of the coalition publishing its paper.

But Garcia said that in discussions with CISA, “increasingly, I think they understand that there might be a need” for an OT BOD.

Nearly nine out of 10 federal civilian executive branch agencies failed to meet last summer’s deadline to implement cloud security directives from the Cybersecurity and Infrastructure Security Agency, a watchdog report published Wednesday found.

The conclusions from those results, according to the inspector general for the Department of Homeland Security: agencies “may encounter elevated security exposures that undermine the national cloud security posture and increase the likelihood of preventable cyberattacks and related threat,” and “CISA lacks the authority necessary to require full and timely implementation of Binding Operational Directives,” or BODs.

The latter is a question that has surfaced before about CISA directives, which the agency uses to pressure agencies into improving their cyber defenses. 

The IG took a look at the Secure Cloud Business Applications (SCuBA) project, created in response to the 2022 SolarWinds attack. It provides secure configuration baselines, settings and assessment tools to help agencies reduce the risk of breaches.

A December 2024 directive gave agencies a list of requirements to align with SCuBA, with a deadline of June 2025.

The IG found that 88 of 102 agencies, or 86%, didn’t implement all the mandatory SCuBA policies from BOD 25-01. As of February of this year, “compliance with BOD 25-01 had not improved. A total of 78 out of 102 (76%) [Federal Civilian Executive Branch] agencies were still not in compliance with implementing all mandatory SCuBA policies.”

“Some examples of baselines that FCEB agencies did not implement included blocking outdated authentication procedures, enforcing multifactor authentication, and implementing a policy to protect sensitive and personally identifiable information,” the IG report states. “Implementation of these baselines could mitigate vulnerabilities and threats from affecting the cloud business applications.”

That’s the result of CISA’s lack of power to enforce its BODs, which translates into greater risk, the IG concluded.

“Without defined enforcement oversight of SCuBA policy compliance, the Federal cloud security posture across the Federal enterprise is weakened,” the report states. “When agencies do not adopt required configurations or meet implementation deadlines, their cloud environments remain exposed to preventable threats.”

CISA didn’t respond to the report, according to the IG. 

The agency didn’t immediately respond to a request for comment from CyberScoop.

A group of leading House Democrats introduced legislation Monday requiring the Cybersecurity and Infrastructure Security Agency to conduct an assessment of its workforce to determine whether it’s up to the task after the exit of around 1,000 employees during President Donald Trump’s second term.

The concept of a force structure assessment is more common in military branches, including one that Congress previously ordered for Cyber Command. The CISA Force Structure Assessment Act would order the agency to carry out a review of whether the agency still has the necessary personnel, training and certifications after budget cuts and other Trump-era departures.

“America’s cyber defenses are only as strong as the people behind them,” Rep. James Walkinshaw, the Virginia Democrat serving as lead sponsor of the bill, said in a news release. “As cyber threats grow more sophisticated and technologies like artificial intelligence and quantum computing reshape the threat landscape, Congress needs a clear accounting of whether CISA has the workforce, skills, and resources required to keep Americans safe and enable mission delivery. This legislation will identify critical gaps and give Congress concrete information to address them.”

Also sponsoring the bill are the top Democrat on the House Homeland Security Committee, Bennie Thompson of Mississippi, and the top Democrat on its cybersecurity subcommittee, Delia Ramirez, D-Ill.

Additional elements of the force structure assessmewould include a review of the security of federal IT systems and support for state and local governments; the risks posed by AI, quantum computing and other cutting edge technologies; CISA’s threat-hunting and incident response capabilities; support for critical infrastructure and operating technology, including CISA’s role as a sector risk management agency for a number of industry sectors; the operation of the Joint Cyber Defense Collaborative; and international cooperation.

Some lawmakers and other observers have worried those areas have been greatly impacted by staffing cuts, ultimately hurting CISA’s ability to carry out its core functions.

Ramirez dinged GOP lawmakers for “a lack of interest in safeguarding our nation’s cybersecurity and our residents’ civil rights and privacy” in going along with the CISA cuts and other developments at the Department of Homeland Security.

Lawmakers on both sides of the aisle have voiced concern about the scope of cuts at CISA, but Republicans have approved some of them while pushing back on others. CISA itself is currently seeking to hire hundreds of new personnel, even as its latest budget blueprint calls for yet more funding reductions.

“With Iran targeting our critical infrastructure and frontier AI models creating new cyber risks, we must ensure we have a cybersecurity workforce to counter these growing threats,” Thompson said. “After Trump has spent the past two years targeting and slashing CISA’s workforce, we need the agency to assess if it has [the] right personnel in place to fulfill its mission.”

National Cyber Director Sean Cairncross has discussed White House plans to develop a cybersecurity academy meant to consolidate and enhance existing federal cyber training and education programs, with the aim of addressing cyber workforce shortages. His office has reportedly drafted an executive order that would establish that academy.

A Cybersecurity and Infrastructure Security Agency program that provides tools and capabilities to other agencies has to get speedier so it can push them toward being able to move more quickly themselves, an agency official said Tuesday.

“We have to get faster,” said Richard Grabowski, acting branch chief of service delivery and deputy program manager for the Continuous Diagnostics and Mitigation program at CISA. “The way that we collaborated today wasn’t fast enough for the threats of yesterday, and they certainly aren’t going to be fast enough for the threats of tomorrow.”

That means pushing responsible automation of tasks that also can do so at scale, he said, so that experts “can focus more [on] dealing with the novel threats and adoption and tuning of advanced technology, and not hitting alerts every other day.”

Velocity is one of the three core goals for the CDM program, along with unification and data-driven risk management, Grabowski said at the Elastic Federal Cyber Defense Breakfast, produced by FedScoop.

Unification means keeping data out of silos so “we are connecting those deployments in a meaningful way to really stimulate reusable, actionable lessons learned,” Grabowski said. And data-driven risk management means that in the event of a crisis-level event, agencies are able to “see what is happening with timely, accurate, and trustworthy data, so that we are the tool of first response when the things hit the fan.”

One of CDM’s offerings is Security Information and Event Management (SIEM) as a Service, a cloud-based platform for threat analytics, incident response and more. Grabowski said there’s a three-year roadmap for expanding and enhancing it, including by ramping up staff and conducting training.

Mike Duffy, the acting federal chief information security officer, said at the same event that three principles should guide what comes next for CDM. One is aggregating demand across agencies that share common problems: “When agencies need the same capabilities, we should use federal scale to improve security, interoperability and value.”

Second, he said, “is buying outcomes, not product” by making it clear what outcomes the federal government is seeking and then allowing commercial markets room to innovate. 

Duffy said the third was to “design acquisition for continuous improvement,” meaning making sure that acquisition models promote competition and opportunities for new capabilities to enter.

“Now is not the time to set capabilities and move on for the next 10 years,” he said. “Mow that agile mindset of how we can continue to deliver and deploy capabilities based on the threats we’re seeing to reduce risk at scale across the federal government — that is absolutely key.”

CDM has been evolving since the SolarWinds breach that compromised at least nine federal agencies, said Matt House, CISA’s acting associate director and program manager for CDM.

“Post-SolarWinds, one of the things that that the government took away was, we lack what I would say is a common operating picture with respect to the operational visibility we need to be able to assess and coordinate response government wide,” House said at the event.

When the Cybersecurity and Infrastructure Security Agency tested defenses for two targets — one in the government sector and the other in the water sector — red teamers were able to get into both of their systems, but the water organization discovered the simulated attack and acted to defend itself, whereas the government organization did neither.

CISA published the breakdown Tuesday in a rare public report on its red-team activities, at a time when attacks on the water sector have a higher profile after revelations of targeting of water facilities across the United States over the past month and numerous government warnings.

The agency didn’t name the organizations it tested through a process that is voluntary and by-request.

“In one organization (Organization A), the team gained initial access to multiple workstations, gained elevated privileges over the domain, and moved laterally to [sensitive business systems] and cloud resources undetected,” CISA’s analysis reads. “In the second organization (Organization B), network defenders quickly detected the initial compromise and quarantined the affected systems.”

For “Organization A,” the government organization, CISA used an internal email address to send phishing emails to gain access to the workstations, probed further to gain elevated privileges, then moved around and compromised targeted sensitive business systems. The red teamers observed that the organization “did not respond effectively to red team activity” by accessing personnel emails at its security operations center, where they saw them receive low- and medium-severity endpoint detection and response alerts, but didn’t respond to them.

False positives by the thousands, including some with higher severity, “obscured the alerts triggered by red team activity,” CISA said. The agency also faulted “organizational silos.”

Meanwhile, at “Organization B,” the water organization, CISA got access via a spearphishing campaign, convincing three users to click on a malicious link to gain access to workstations. This time, the security operations center triaged the alerts and quarantined the work stations in 2, 10 and 20 minutes, respectively.

The red teamers tried another approach with the help of the organization’s IT contacts who were aware of the activity, but were foiled in their follow-ups.

“Because Organization B detected the initial compromise, the red team moved to an ‘assume breach’ model, where Organization B trusted agents (TAs) provided access to a host that replicated the level of access the red team would have had if defenders had not detected their activity,” CISA wrote. “From there, the red team escalated privileges and moved laterally to [sensitive business systems], cloud resources, and a bastion host in the OT [operational technology] demilitarized zone (DMZ), where defenders again detected activity and isolated the system.”

Still, CISA said both organizations had flaws in their defenses: They underestimated cloud risks; they lacked Conditional Access — a Microsoft security tool — for workload identities; and they didn’t have processes in place to revoke compromised access/refresh tokens.

CISA first published an advisory on its red team activity in 2023, but such advisories have been few and far between since. The agency said last year that it had not “laid off” its red team, after stories revealed the exit of contractors that included red-team members.

The Cybersecurity and Infrastructure Security Agency published a guidebook for federal agencies Thursday to aid them on managing security risks with open-source software, touching on topics like patching and open-source AI models.

An executive order President Joe Biden signed and that President Donald Trump amended ordered CISA and other agencies to issue open-source security recommendations to federal agencies. But the guidance is also timely, given a recent slew of attacks on open-source software (OSS).

“As part of our statutory mission, CISA remains laser-focused on enhancing the nation’s cybersecurity by collaborating with government, industry and the open-source community to understand and securely use OSS,” said Chris Butera, acting executive assistant director for cybersecurity. “CISA encourages federal civilian agencies to review this guide and implement the principles and practices to improve risk management, better execute their mission, and better serve the public.” 

The document, “Open Source Software: Security Principles and Practices,” touts the advantages of open-source software — which anyone can use, modify and share — as offering benefits in efficiency, cost, security transparency and more, but notes that it also has unique tradeoffs.

“All software carries risk, and OSS is no more or less risky than other software. The key distinction is that, with OSS, agencies can directly assess code quality and security, rather than relying solely on vendor assurances,” the guidance reads. “OSS is increasingly intertwined with emerging technologies such as artificial intelligence. Agencies that adapt to OSS’s unique characteristics will position themselves to meet future challenges and leverage new innovations.”

The guidance says that agencies need to take steps to evaluate the trustworthiness of an OSS project before approving an OSS component for use, and track OSS in their asset management repositories. It details how agencies should deal with patching, including when there’s a new OSS vulnerability that doesn’t have one. It offers advice on how agencies might contribute to OSS projects, produce them and secure rights for government reuse of code when contracting for custom software development. And it explains how it should approach open-weight AI models.

“Agencies should approach ‘open source’ AI systems differently from other OSS because open source licenses for AI software do not require the level of transparency needed to evaluate the trustworthiness of the software,” the guidance states.

Æva Black, an open-source security expert and former OSS lead at CISA, said she applauded her former agency for the guidance, telling CyberScoop that it “demonstrates a grounded understanding of the global, diverse, and participatory nature of open source software development, and provides essential guidance for federal agencies to safely use open soure during a crucial moment.” 

She singled out its recommendations on the risks of deploying unverifiable open-weight AI models on sensitive networks.

“Due to recent advances in AI, particularly in large language models capable of finding and exploiting software vulnerabilities, vulnerability management is facing a global crisis,” she said. “Many proprietary software vendors are using this as an opportunity to spread ‘fear, uncertainty, and doubt’ about open source in order to capture public attention, and, I presume, public money — but when used responsibly and maintained collaboratively, I believe open source software is, and will remain, the safest and most cost-effective means for building large scale public infrastructure.” 

CISA has produced a bevy of security guidance and updated advisory materials this week: on the creation of software bills of materials written in conjunction with other agencies and allied governments that won praise from experts; on the isolation of vital operational technology during a crisis, also written with other agencies and allied governments; and the release of updated secure cloud configuration baselines for Google Workspace.
