VLCM Cybersecurity Alerts - July, 2019

 

cybersecurity---july

 

Things really started heating up in July, especially regarding ransomware attacks targeting cities across the US. Some of the first attacks started in Baltimore, Atlanta, then cities in Florida and recently Georgia. The Governor of Louisiana recently declared a state of emergency after ransomware attacks were reported by public schools in several Parishes. This activity prompted a recent joint statement by the Cybersecurity and Infrastructure Security Agency (CISA), the Multi-State Information Sharing and Analysis Center (MS-ISAC), the National Governors Association (NGA), and the National Association of State Chief Information Officers (NASCIO), urging government and private organizations to reinforce their ransomware defenses. Key recommendations are to ensure critical systems are backed up to offline sites, ensure employee security awareness training is being conducted, with a focus on email phishing-awareness, and to create and/or update incident response plans to include steps to report attacks immediately to the FBI and request assistance from cyber first responders like CISA and the MS-ISAC. VLCM urges customers to stay informed, implement the recommended protections and let us help you stay secure!

 

CIS Releases Newsletter on Cleaning Up Data and Devices

July 31, 2019

Steps to Safeguard Against Ransomware Attacks

July 30, 2019

The Cybersecurity and Infrastructure Security Agency (CISA), Multi-State Information Sharing & Analysis Center (MS-ISAC), National Governors Association (NGA), and the National Association of State Chief Information Officers (NASCIO) have released a Joint Ransomware Statement with recommendations for state and local governments to build resilience against ransomware:

  1. Back up systems—now (and daily). Immediately and regularly back up all critical agency and system configuration information on a separate device and store the backups offline, verifying their integrity and restoration process. If recovering after an attack, restore a stronger system than the one lost, fully patched and updated to the latest version.
  2. Reinforce basic cybersecurity awareness and education. Ransomware attacks often require the human element to succeed. Refresh employee training on recognizing cyber threats, phishing, and suspicious links—the most common vectors for ransomware attacks. Remind employees of how to report incidents to appropriate IT staff in a timely manner, which should include out-of-band communication paths.
  3. Revisit and refine cyber incident response plans. Have a clear plan to address attacks when they occur, including when internal capabilities are overwhelmed. Make sure response plans include how to request assistance from external cyber first responders, such as state agencies, CISA, and MS-ISAC, in the event of an attack.

CISA encourages organizations to review the Joint Ransomware Statement and the following ransomware guidance:
