How DNS history can help with security investigations – Guide
DNS monitoring is used to manage and ensure the security of direct communications between browser users and the websites and services they use. Regardless of whether your company is responsible for managing one or multiple website domains, DNS monitoring can help you quickly diagnose problems, prevent targeted attacks, and easily detect any security breaches that may occur. Effective DNS monitoring consists of regularly checking DNS records for unexpected changes or local outages (whether due to manual error or hacking). This allows your team to quickly identify and resolve any issues that could negatively affect your site or the safety of your users who need to access your site.
Domain Name System (DNS) records contain information about a specific domain name. These records include, but are not limited to, the corresponding Internet Protocol (IP) address, Mail Exchange server (MX), and name server (NS). Malicious actors can use these DNS records to resolve malicious IP addresses. However, as these DNS records are the only ones that resolve the malicious IP address at the time of writing, this could indicate involvement in suspicious activity.
DNS history can help with security investigations
Detect potentially malicious domains
Domain name resolution (DNS) history is an important tool for businesses. DNS history can help identify which domains resolve to the same IP address, which can be useful for tracking down malicious activity. Additionally, DNS history can provide information about which domains a user has visited. This information can be helpful in understanding user behavior and in marketing campaigns. ..
These domains and subdomains are not reported as malicious, so they cannot be flagged by security systems that do not implement IP-based blocking and monitoring. However, as they are the only ones to resolve the malicious IP address (at least at the time of writing), this could indicate involvement in suspicious activity. Networks are more secure when security teams examine traffic to and from these domains and subdomains.
Cybersecurity experts have discovered that various types of cyberattacks can be mitigated by discovering domains associated with malicious IP addresses. For example, a phishing campaign using malicious IP addresses can be stopped by identifying the domains associated with those IP addresses. Additionally, malware campaigns using domain names as weapons can be stopped by finding the corresponding websites and disabling access to them.
Help prevent and recover from DNS hijacking
DNS hijacking is a common type of DNS attack, where threat actors change your DNS settings after gaining unauthorized access to your system. They may change IP resolutions to redirect your site visitors to a site under their control. This can result in loss of data and inconvenience for your users. To protect yourself from DNS hijacking, regularly track your DNS history records.
This website is a gateway for attackers to steal sensitive information from users on your network. However, if you can immediately detect a sudden change in IP resolution by monitoring DNS history, you can investigate and mitigate attacks before they do any more damage. Additionally, accessing your historical DNS records also helps to restore them and correct changes made by attackers.
Protect brand reputation
Preventing and detecting cyberattacks early is a form of brand protection, as these processes help prevent reputational damage caused by cybercrimes. In addition to dubious IP addresses, DNS history lets you stay away from suspicious cyber resources such as NSs and email servers that attackers can use by detecting them before allowing them to access your network.
DNS history can be used to detect malware C&C servers. This allows organizations to combat denial-of-service (DoS) attacks. Botnets often communicate with C&C servers, so shutting down these servers would help stop the attack. ..
