Hygiene: While not part of the incident response playbook, good security hygiene and following industry security practices is important in staying proactive against cyber threats. SonicWall will work with the affected customers to upgrade them to newer firmware. When the SMA 100 has a confirmed security incident after our internal analysis, customers are notified by SonicWall support. Recovery: This phase involves bringing an affected SMA 100 back to normal operations to avoid future incidents. To achieve this, suspicious processes are terminated, and unauthorized files are removed from the operating system. This involves restricting specific network communications from the SMA 100 to avoid communications to malicious servers.įigure: SMA 100 Incident Response MethodologyĮradication: If SMA 100 has been deemed to be compromised, eradication is the process of trying to eliminate the root cause of the incident and either evict the adversary or mitigate the vulnerability that may have enabled the adversary to enter the environment. If the SMA 100 is deemed to have deviated from normal behavior, short-term containment is performed. If a security incident is discovered on the local system, additional diagnostic metadata is collected from the operating system to determine the root cause of the incident.Ĭontainment: After detecting a potentially malicious event, it is important to contain the intrusion before an adversary can access more resources and cause further damage. Further analysis is done to determine if these aberrations represent actual security incidents. SMA 100 10.2.1.7 follows the NIST incident response playbook of detection and analysis, containment, eradication, and recovery.ĭetection & Analysis: The SMA 100 10.2.1.7 continuously monitors the operating system (also called firmware) for any anomalous behavior and deviations from normal operations. SMA 100 Security Enhancements with NIST 800-61 In addition, SonicWall sends anonymous encrypted data to backend servers, including device health data, to detect and confirm security events and release new software to correct the issue. SonicWall has taken the approach of incorporating security enhancements in their products, such as the SMA 100 series, which helps identify potentially compromised devices by performing several checks at the operating system level and baselining normal operating system state. SMA 100 Series release 10.2.1.7 includes several key security features that protect the operating system from potential attack as well as updates to the OpenSSL Library. SonicWall Secure Mobile Access (SMA) 100 Series is a unified secure access gateway that allows organizations to offer remote users virtual private network (VPN) access to their corporate applications. rsa() - RSA key processing tool rsautl() - RSA utility s_client() - SSL/TLS client program s_server() - SSL/TLS server program s_time() - SSL/TLS performance timing program sess_id() - SSL/TLS session handling utility smime() - S/MIME utility speed() - test library performance spkac() - SPKAC printing and generating utility verify() - Utility to verify certificates.As part of SonicWall’s commitment to performance, security and usability, we are introducing SMA 100 Series release 10.2.1.7.
