Description
Technical Field
The present invention relates to the field of computers, and more particularly, to a method, apparatus, device, and readable medium for brute force detection of SSH services in a container.
Background
The fail2ban is a piece of utility software on the linux system, can monitor the system log, then perform corresponding shielding action on error information (regular matching) matched with the log, can support a large number of services, such as sshd, apache, qmai, profitpd, sasl, etc., the implementation mechanism of the fail2ban is a filtering and screening device for log IPs, finds out these "misbehaving" IPs from the log according to different prison rules, once these IPs send requests of offending prison rules to reach a threshold value, the IPs can directly block and shield the IPs, and the time for shielding the IPs can be set for a long time to avoid the damage caused by accidental injury. The most important thing to use fail2ban is how to make effective prison rules according to the log, and after the rules are made, whether the rules are effective or not needs to be tested, and whether the rules are effective or not can achieve the expected purpose.
The docker container is an open-source application container engine, so that developers can package their applications and dependency packages in a uniform manner into a portable container and then distribute the package to any server (including popular Linux machines and windows machines) provided with the docker engine, and virtualization can be realized. After SSH (Secure Shell, a security protocol established on the basis of an application layer) service is opened in the docker container, fail2ban can be used for brute force cracking detection. However, when the fail2ban is directly installed and is not configured like a host using the container, it is found that the fail-safe is not effective. Because SSH services are opened when a docker container is used, but because no rsyslog is opened in the container, fail2ban dependent/var/log/auth. That is to say, the use of fail2ban is strongly dependent on the rsyslog service, however, the container without privilege added cannot open the function that the service cannot use iptables and the like, and if privilege is added to the container, the user of the container has the user right of the host root, which causes a great security risk.
