Configuring IDS Rules for Optimal Protection with Azure Firewall IDS Protection
Azure Firewall IDS Protection provides a comprehensive set of IDS rules that can be used to detect and block a wide range of threats. These rules can be configured to suit the specific needs of an organization.
Default IDS Rules
Azure Firewall IDS Protection comes with a default set of rules that are enabled by default. These rules are designed to protect against common threats, such as:
- Port scans: Scans of common ports, such as TCP port 21 (FTP) and TCP port 22 (SSH), to identify open ports that can be exploited by attackers.
- Brute force attacks: Repeated attempts to guess a password or other authentication credentials.
- Denial-of-service attacks: Attacks that attempt to overwhelm a system with traffic, causing it to become unavailable.
- SQL injection attacks: Attacks that attempt to exploit vulnerabilities in SQL databases.
- Cross-site scripting attacks: Attacks that attempt to inject malicious code into a website or web application.
Custom IDS Rules
In addition to the default rules, organizations can create their own custom IDS rules. Custom rules can be used to detect and block specific threats that are unique to an organization’s environment.
Best Practices for Configuring IDS Rules
When configuring IDS rules, it is important to consider the following best practices:
- Use a layered security approach: IDS rules should be used in conjunction with other security measures, such as firewalls, intrusion prevention systems, and security information and event management (SIEM) systems, to create a strong layered security posture.
- Enable only the rules that are necessary: Enabling too many rules can increase the risk of false positives, which can overwhelm security teams and make it difficult to identify real threats.
- Tune rules to reduce false positives: IDS rules can be tuned to reduce the number of false positives. This can be done by adjusting the sensitivity of the rules and by using negative filters to exclude specific types of traffic from being inspected.
- Monitor IDS alerts: IDS alerts should be monitored regularly to identify potential threats. Alerts should be investigated promptly and appropriate action should be taken to mitigate any threats that are identified.

Investigating IDS Alerts
When an IDS alert is received, it is important to investigate the alert promptly to determine if it represents a real threat. This may involve:
- Gathering additional information about the alert, such as the source of the attack, the target of the attack, and the type of attack.
- Analyzing network traffic logs and other security data to identify additional indicators of compromise.
- Contacting the affected system owner to determine if they are aware of the attack and if they have taken any action to mitigate the threat.
Responding to IDS Alerts
If an IDS alert is confirmed to be a real threat, it is important to take immediate action to mitigate the threat. This may involve:
- Isolating the affected system from the network to prevent the spread of the infection.
- Remediating the vulnerability that was exploited by the attack.
- Updating security policies to prevent similar attacks from succeeding in the future.
