RM Alert: Steps to Take to Protect Against a Cyberattack

Malicious attacks on your business can cripple operations. With the recent tensions in the Russia-Ukraine crisis, those crippling effects are closer than you think. At Pharmacists Mutual, we take government warnings seriously and aim to circumvent any malicious attacks upon our members. Federal cybersecurity professionals have issued warnings to American businesses that we should all heed.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warns of possible retaliation from Russia. Organizations should be on high alert in the coming days and weeks. CISA stands ready to help organizations respond to cyberattacks. CISA has provided “Shields UP” guidance for all organizations in the wake of current tensions. The complete program can be viewed at https://www.cisa.gov/shields-up and is detailed below.

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

Take steps to detect a potential intrusion quickly

  • Ensure cybersecurity/IT personnel are focused on identifying and quickly assessing any unexpected or unusual network behavior. Enable logging in to investigate issues or events better.
  • Confirm 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 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 all participants understand their roles during an incident.

Maximize the organization’s resilience to a destructive cyber incident

  • Test backup procedures to ensure critical data can be rapidly restored if the organization is impacted by ransomware or a destructive cyberattack; ensure backups are isolated from network connections.
  • If using industrial control systems or operational technology, conduct a test of manual controls to ensure critical functions remain operable if the organization’s network is unavailable or untrusted.

By implementing the steps above, all organizations 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.

Recommendations for Corporate Leaders and CEO’s

Corporate leaders have an important role to play in ensuring 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 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 attacks 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 so, senior management should participate in a tabletop exercise to ensure familiarity with how your organization will manage a major cyber incident, 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 such systems have been identified and continuity tests have been conducted to ensure 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 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 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.
