I redisigned a instant script from internet that blocks IP_addresses attackers. Original version works by time intervals, my variant reacts quickly, the attacker is blocked when fails counter is exceeded.
- Event logging of attacks sources with timestamps and logins write on the disk;
- Blocking will made, if fails counter exceeded while number of setted days is not reached.
- System requierments: enabled Windows Firewall, Powershell. Files access time is not disabled. Works by default since Windows 10;
- In older versions of Windows, this script only registers parameters attacks parameters, not made blockings, but can be combine, for example, with IDDS Cyberarms Intrusion Detection;
- Install and remove script, reset created by him blocks require administrator rights;
- Manual script uninstall. Manual is attached;
- Blocking made not momentum when counter execeeded, but not long time (less that minute). The logic of the original script is more apllicable for tens of minutes.
- Fast reaction;
- Eventlog can help catch slow attackers;
- Not require install additional software, low system load.
- Manual unblock attackers address;
- There are no blocking warnings;
- Not implemented log rotation;
