IP abuse signals for blocking threats are a common threat to online activities, quietly eroding trust and leading to blacklists, disrupted service, and resource misuse. Fortunately, there are proven ways to identify and stop it.

An IP address is a unique numerical label assigned to devices connected to the internet, enabling data exchange between them. It’s also the primary way that online activity is identified. When exploited, an IP address can be used for malicious activities like brute force attacks, credential stuffing, spamming, and click fraud.

• Using IP Abuse Signals to Block Online Threats Proactively

When an attacker tries to access your systems, their IP address is your first clue about their intent. An IP reputation check enables you to determine an attacker’s risk in milliseconds, giving you the confidence to block them or prompt them for multi-factor authentication.

With the help of a network security platform, you can use real-time abuse information from global threat feeds, community reports, honeypots, and more to create a custom list of risks. This enables you to prioritize the most dangerous threats and make decisions about blocking, alerting, or flagging for further review.

As abuse behaviors evolve, a blocklist can quickly become out-of-date. This is why it’s essential to have a process in place for regularly reviewing the blocklist and removing outdated entries. Otherwise, false positives will drain analyst time and cause unintended access issues and policy sprawl. Accelerynt’s open-source IP blocklist playbooks automate this cycle from start to finish, so you can spend more time on higher-value activities.
