Individual computers assigned for the performance of certain service tasks are called servers. By definition, such a device is available at the local and public network. Immediately, the fact that the service computer has access to the Internet implies that there are potential threats that require server security configuration.
The main types of attacks
There are several common ways to bring down the server:
- 1. DoS, and DDoS attacks, resulting in server overload and temporary restriction of access to it. DDoS attacks are the more dangerous ones, as the attack utilizes many computers and many connections.
- 2. Brute-Force - login and password guessing attempts to login to the service computer. Usually performed by an automated system.
- 3. Attack by exploiting vulnerabilities in scripts.
Most of these threats can be prevented in advance by following the "rules of etiquette" of computer security. One of the principles of prevention of attacks on the server is to follow the recommendations of the developers of the particular OS that you're using.
One of such recommendations is a timely update of the system and specialized software. Some of the updates fix the vulnerabilities discovered by the developers.
Another necessary element of protection is to use packet pre-filtering for network intrusion detection. This is done in two ways.
The first - to install a firewall and set up proper configurations. This is a must for any device that has Internet access.
The second way is the implementation of intrusion detection systems (IDS). It is similar in functionality with a firewall, however, further analyzes traffic based on known signatures and a special heuristic algorithm.
To avoid password cracking, use a complex password combination. It is desirable to use a combination of different groups of symbols, with a total length of at least 16 units. And, what's quite obvious, every service has to have a different password.
The solution to any important task should be performed by a specialist. Selection of a firewall, its configurations, the server encryption, as well as non-standard configuration - all of these security measures require a professional approach, which our specialists will provide for you.
