Incident Response Planning:
Segment Your Data
First, critical data and affected systems on your networks should be segmented. Too often, companies store all of their data in one place meaning that if a cyberattack occurs they may be in a position to lose everything. By segmenting your data you ensure that if a breach does occur, losses will be far less severe than they otherwise would.
Have an IRP: Incident Response Plan
An Incident Response Plan is absolutely critical to ensuring that your organization can respond quickly and effectively to a security incident. An IRP should designate an individual to be responsible if an incident does occur, along with an incident response team to aid that person. It should include elements such as how to report a suspected incident, who to call, and what measures should be taken immediately to reduce the impact of the data breach. After an incident, you should discuss lessons learned.
Perform Threat Hunting
Threat Hunting involves proactively hunting for vulnerabilities before the incident occurs. This can help familiarize your team with the network and data storage locations as well as get them experience in searching for potential compromise. You can use threat intelligence software while performing threat hunting or use a SIEM or security operations center. You can also empower and secure your business using open-source security tools like intrusion detection systems and open-source threat intelligence feeds. You should also consider how your IR plan will impact your security policy in the short term and long term. In addition, ensure that you have active network monitoring services.
Train Your Employees
Your employees need to know what to do right away if an incident occurs. In many cases, untrained employees may ignore a security incident, or worse yet try to hide it out of fear of repercussions. This can cost your company valuable time in which you could be responding to a breach. Security Awareness Training is one of the most cost-efficient ways to reduce the risk of breaches and incidents. Studies show security-related risks are reduced by 70% when businesses invest in cybersecurity awareness training. Humans and technology need to work together to detect and respond to cyber threats. Management of the urgent IT security problems like social engineering, spear-phishing and ransomware attacks is an absolute must if companies expect to stay safe.
