Incident Response from A to Z: Everything to Know!
Incident response is a method that everyone in the industry knows about. However, companies can use different methods in incident response. While some of these methods are successful, some may fail. We have compiled what you need to know about incident intervention in order to eliminate the question marks in your mind about incident response. Here is Incident Response from A to Z!
Incident Response from A to Z
Before describing the details of the incident response, we wanted to explain what this method is with a small example. Let’s say you are the security officer of a company. At our company, you use anti-phishing email filtering tools for protection. But suspicious emails can bypass these systems. To detect these emails, you use a button that allows your employees to report suspicious-looking emails. This is where the incident response comes into play. When your employees press this button, the suspicious email goes to the security team. In addition, incident response tools dump email to the Deleted Items folder or the Junk folder.
But your job as a security officer doesn’t stop there. You have to create a system that will reply to these emails end-to-end. With automation, you should reduce manual effort and response time. So how can you do that?
Incident Response from A to Z: Steps You Should Follow
1. Email Classification
When your employee encounters a suspicious email, this email is examined directly and incident response tools determine whether the email is suspicious or not. You can specify a generic message template to send to your employees to automate this step. The message should include a guidance section, some tips for catching phishing emails, and details of the analysis. In this way, you will automatically inform your employees. If the email is genuine or spam, your job will be done here. However, if you suspect that the email sent is a phishing email, you should continue with the process.
2. Phishing Detection
If you suspect that the email is a phishing email, you have two different options. The first is to get to work on spear-phishing detection. Unfortunately, this step is very difficult to automate because detailed research is required. Your second option is to check whether the links or attachments in the email are malicious. You can easily automate this step and shorten your detection time. After this section, you should examine individual links and attachments.
3. Inspecting Malicious Links
If you suspect that the email contains malicious links, you should conduct an integrated study with other systems. In this study, you should effectively use Proxy servers, Microsoft Office links analysis tool, Microsoft Defender, and Threat Intelligence tools. These tools will help you identify all users in your company and outside of the company who may have clicked on the malicious link.
You should also check for malicious files on the link. To do this, first, analyze the status of the connection. If you want to automate this process as well, you can make various investments, but make sure you don’t spend too many resources on detecting malicious files.
By looking at the logs, you can identify people or devices that clicked on the link. You should then block all paths to the connection, and you can automate this process. The link report with a list of potential clickers will tell you what to do. You can then start an automatic scan on these devices.
4. Analyzing Malicious Attachments
This step includes pretty much the same step as examining malicious links. If you suspect the presence of malicious attachments, you should analyze the files contained in the phishing email. Afterward, it would be best to use Threat Intelligence to check the areas where the malicious file is used or the links or domains associated with this file. If the file is associated with a malicious link, you should automatically repeat the above step. Afterward, you have to check the existence of the file on the end-user computers with the help of various applications. Finally, make sure to block all access paths to the file and scan for any affected devices.
