CISA recommends all organizations—regardless of size—adopt a heightened cybersecurity posture.
"They list a number of highly valuable cybersecurity hardening recommendations that all organizations should take very seriously."
The Cybersecurity and Infrastructure Security Agency (CISA) released a ‘Shields Up’ Advisory. Within here they note that cyber threats have increased substantially, most notably from the Russian government. They list a number of highly valuable cybersecurity hardening recommendations that all organizations should take very seriously.
The CISA also notes that right now it’s very important to empower CISOs to strengthen the security of your organization.
“Empower Chief Information Security Officers (CISO): In nearly every organization, security improvements are weighed against cost and operational risks to the business. In this heightened threat environment, senior management should empower CISOs by including them in the decision-making process for risk to the company, and ensure that the entire organization understands that security investments are a top priority in the immediate term.”
We strongly suggest that all of our clients review and follow the recommendations of the CISA, verify you’ve met or exceeded all of the CISA advisory’s recommendations. If you need any assistance or advice on how to meet their objectives please let us know.
Every organization in the United States is at risk from cyber threats that can disrupt essential services and potentially result in impacts to public safety. Over the past year, cyber incidents have impacted many companies, non-profits, and other organizations, large and small, across multiple sectors of the economy.
Notably, the Russian government has used cyber as a key component of their force projection over the last decade, including previously in Ukraine in the 2015 timeframe. The Russian government understands that disabling or destroying critical infrastructure—including power and communications—can augment pressure on a country’s government, military and population and accelerate their acceding to Russian objectives.
While there are not currently any specific credible threats to the U.S. homeland, we are mindful of the potential for the Russian government to consider escalating its destabilizing actions in ways that may impact others outside of Ukraine.
Based on this situation, CISA has been working closely with our critical infrastructure partners over the past several months to ensure awareness of potential threats—part of a paradigm shift from being reactive to being proactive.
Many critical infrastructure or state, local, tribal, and territorial governments may find it challenging to identify resources for urgent security improvements. CISA has established a catalog of free services from government partners, the open source community, and JCDC companies to assist with this critical need.
Shields Up Guidance for All Organizations
CISA recommends all organizations—regardless of size—adopt a heightened posture when it comes to cybersecurity and protecting their most critical assets. Recommended actions include:
Reduce the likelihood of a damaging cyber intrusion
Validate that all remote access to the organization’s network and privileged or administrative access requires multi-factor authentication.
Take steps to quickly detect a potential intrusion
Ensure that cybersecurity/IT personnel are focused on identifying and quickly assessing any unexpected or unusual network behavior. Enable logging in order to better investigate issues or events.
Confirm that the organization's entire network is protected by antivirus/antimalware software and that signatures in these tools are updated.
If working with Ukrainian organizations, take extra care to monitor, inspect, and isolate traffic from those organizations; closely review access controls for that traffic.
Ensure that the organization is prepared to respond if an intrusion occurs
Designate a crisis-response team with main points of contact for a suspected cybersecurity incident and roles/responsibilities within the organization, including technology, communications, legal and business continuity.
Assure availability of key personnel; identify means to provide surge support for responding to an incident.
Conduct a tabletop exercise to ensure that all participants understand their roles during an incident.
Maximize the organization's resilience to a destructive cyber incident
Test backup procedures to ensure that critical data can be rapidly restored if the organization is impacted by ransomware or a destructive cyberattack; ensure that backups are isolated from network connections.
If using industrial control systems or operational technology, conduct a test of manual controls to ensure that critical functions remain operable if the organization’s network is unavailable or untrusted.
Corporate leaders have an important role to play in ensuring that their organization adopts a heightened security posture. CISA urges all senior leaders, including CEOs, to take the following steps:
Empower Chief Information Security Officers (CISO): In nearly every organization, security improvements are weighed against cost and operational risks to the business. In this heightened threat environment, senior management should empower CISOs by including them in the decision-making process for risk to the company, and ensure that the entire organization understands that security investments are a top priority in the immediate term.
Lower Reporting Thresholds: Every organization should have documented thresholds for reporting potential cyber incidents to senior management and to the U.S. government. In this heightened threat environment, these thresholds should be significantly lower than normal. Senior management should establish an expectation that any indications of malicious cyber activity, even if blocked by security controls, should be reported, as noted in the Shields-Up website, to CISA or the FBI. Lowering thresholds will ensure we are able to immediately identify an issue and help protect against further attack or victims.
Participate in a Test of Response Plans: Cyber incident response plans should include not only your security and IT teams, but also senior business leadership and Board members. If you’ve not already done, senior management should participate in a tabletop exercise to ensure familiarity with how your organization will manage a major cyber incident, to not only your company but also companies within your supply chain.
Focus on Continuity: Recognizing finite resources, investments in security and resilience should be focused on those systems supporting critical business functions. Senior management should ensure that such systems have been identified and that continuity tests have been conducted to ensure that critical business functions can remain available subsequent to a cyber intrusion.
Plan for the Worst: While the U.S. government does not have credible information regarding specific threats to the U.S. homeland, organizations should plan for a worst-case scenario. Senior management should ensure that exigent measures can be taken to protect your organization’s most critical assets in case of an intrusion, including disconnecting high-impact parts of the network if necessary.
As the nation’s cyber defense agency, CISA is available to help organizations improve cybersecurity and resilience, including through cybersecurity experts assigned across the country. In the event of a cyber incident, CISA is able to offer assistance to victim organizations and use information from incident reports to protect other possible victims. All organizations should report incidents and anomalous activity toCISAand/or the FBI via yourlocal FBI field officeor the FBI’s 24/7 CyWatch at (855) 292-3937 orCyWatch@fbi.gov
