The reality of how organizations deal with the increasing frequency of security incidents, breaches, and data loss is well known among the industry. Firms try to build an efficient incident response plan (IRP) that can deal with security incidents successfully. Incident handling can be performed better when organizations possess adequate resources to maintain the security of their critical infrastructure. These resources not only include tools and software but also training IT staff regarding compliance with industry standards and laws. The employees of the organization should be well aware of different forms of cyberattacks and how they can avoid becoming prey.
Incident handlers, also known as security incident managers, help enterprises to respond to cyberattacks that are capable enough to compromise the confidential data of the firm. These attacks can cause financial as well as reputational loss.
In this blog, we will give you a blueprint to handle a security incident successfully.
The Ultimate Guide to Incident Handling
An impactful incident handling has three key stages – Identification, Containment, and Recovery.
Identification of the Ongoing Attack
For identifying the potential and ongoing attacks, a company needs some level of preparation. The organizations must stay prepared for all kinds of cyber threats. Creating backup copies of all the key data, updating software regularly, and implementing a well-drafted security policy is a must. This process will help in minimizing the effects of a security incident.
After this preparation, the first step in incident handling is to identify the attack. The identification process could be tougher depending upon the complexity and sophistication of the attack. SOC Analysts have clear goals to identify any kind of cyberattacks and raise an alarm whenever detected. These professionals either look for a pattern or characteristics of the known attacks for identification purposes. This first step also includes determining the effects of the attack on local as well as remote networks and systems.
Containment of the Identified Attack
Once the attack has been identified, the responsible security professionals take steps to minimize the attack surface. This step ensures to limit the damage or stop other security systems from getting compromised.
Recovery from the Contained Attack
The recovery phase allows users to evaluate the damage the attack has incurred. Under this phase, the professional looks for the extent of the attack. It is important that the organization conduct a post-analysis of the attack after its containment. The professionals should look for the loophole, attack vector, and other related information. All the findings should be well-documented for future use.
