Our team at Unite Information Technologies (Unite-IT.com) works round the clock to address potential cyber threats and assist our clients in defending against them. Due to the current conflict in Ukraine, concerns about cyber-attack are at heightened levels.
“We’ve seen in the past that Russia has the intent and capability to cause major disruption through cyberoperations,” says Jamie MacColl at the Royal United Service Institute, a UK think tank.
Russia has at least three military units within the GRU, Russia’s military intelligence agency, that are capable of launching cyberattacks, according to research produced for members of the US Congress in February 2022.
The US Cybersecurity & Infrastructure Security Agency (CISA) recommends all organizations—regardless of size—adopt a heightened posture when it comes to cybersecurity and protecting their most critical assets. CISA recommends the following actions:
Reduce the likelihood of a damaging cyber intrusion
- Validate all remote access to your organization’s network and privileged or administrative access requires multi-factor authentication.
- Ensure that your software is up to date, prioritizing updates that address known exploited vulnerabilities identified by CISA.
- Confirm that your organization’s IT personnel have disabled all ports and protocols that are not essential for business purposes.
- If your organization is using cloud services, ensure that IT personnel have reviewed and implemented strong controls outlined in CISA's guidance.
Take steps to quickly detect cyber intrusion
- Ensure that your 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 your 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 your 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 your 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.
By implementing the above steps, you can can make near-term progress toward improving cybersecurity and resilience. In addition, while recent cyber incidents have not been attributed to specific actors, CISA urges cybersecurity/IT personnel at every organization to review Understanding and Mitigating Russian State-Sponsored Cyber Threats to U.S. Critical Infrastructure.
CISA also recommends organizations visit StopRansomware.gov, a centralized, whole-of-government webpage providing ransomware resources and alerts.
CISA is an organization run by the US government,
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.
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.
Recommendations for Corporate Leaders and CEOs
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.
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 to CISA and/or the FBI via your local FBI field office or the FBI’s 24/7 CyWatch at (855) 292-3937 or CyWatch@fbi.gov.
