I hope you had an excellent valentines day community I hope you are having an excellent time and that it has also been a very successful week since there is a lot to do and to contribute to the community in my previous article I was talking about what Endpoint is and the different situations which can be under threat and how to solve the problem in an effective way and with less impact since Endpoint is usually quite vulnerable if maintenance is not given and constant updates take into account that the malicious contents either ransomwares and other Threats are strengthened 10 times more and we must know how to face the situation.
This time I will talk about Windows server in previous articles I mentioned Windows server but this time I will focus more on the subject completely so that it can be understood with basis and how it works and the different threats that it can face and its solutions.
Windows Server
Windows server is defined as part of a system that operates as a server and its primary function is based on the operation of the networks between servers, domain controllers, web servers and files. It is also responsible for playing an important role in server applications. a separate form between them are the most used as are SQL Server and Exchange Server.
Main functions of Windows Server
In order for Windows server to perform its work correctly there is a series of tasks that must be fulfilled to achieve the specific objectives these are part of the functions that must be exercised by windows server.
- Virtualization of the servers: The approach is based on the creation of an environment that maintains the complete virtualization of the servers and at the same time managed.
- Server management: It is based on an environment in the execution of functions designated by the server, in order to be less exposed to attacks, the management and control of the server can be handled collectivelyfrom a single integrated console.
- Integrated services: It is important to emphasize that Windows Server provides platforms in a unified way for web publications that integrate IIS, Asp and NET.
- Clustering: This function allows to reduce interruptions of services and applications in an advantageous way.
- DirectAccess: Allows direct and secure access to the network either through a computer or device, also offers access to shared file resources.
Most common errors in Windows Server
- In many situations, Windows Server usually presents common errors during its process, which I will mention below.
- Problem when creating the user in Active Directory: Many times the established password does not meet the requirements of the password policy.
- The elimination of an Organizational unit: Commonly the object is protected against accidental elimination.
- Duplicate names between users and groups: This happens when trying a group with the same name of some existing user with the same name therefore does not allow the creation of a name already known.
Windows Server Threats
Windows Server suffers a series of threats that are constant due to the certain vulnerability that it has but that can be prevented in time if the measures are taken in an immediate way:
- Low security alphanumeric passwords: this problem insists when the server does not have a sufficiently strong password since many times the cyber aggressors try to decrypt the passwords with a low enough parameter allowing access.
- Remote execution: Part of the vulnerability of the servers would mean that the server service can be executed remotely by cyber aggressors or hackers.
- The easy access of malicious content: It is expected that ransomware and virus attacks become more present when the server is vulnerable, infecting the system and all its files.
Measures to protect Windows Server
We have already defined what Windows Server is, its most important functions, most common problems and the type of threats that are exposed when the server is vulnerable, now the measures to face these problems and thus prevent a negative impact on the server and its components.
- The authentication of passwords that have numeric and alphabetic characters by adding special characters, in addition to changing the passwords regularly depending on the functions performed.
- Elimination of groups and users which are out of operation, this in some way prevents the entry of users outside the server network and keep the servers function separately.
- Delimitation of access to services through the Firewall with configuration parameters.
- Schedule the permit for the archives and directories under the supervision of the fulfillment of certain indispensable requisites to be executed.
- Examine the search for viruses, backdoors, ransomware and other frequent vulnerabilities that may affect the system.
- Update of software and operating system to strengthen the defenses of each and every one of the server components.
- Protect infrastructure through the firewall and ensure that it is running, it is necessary to be active all the time.
- Make a backup of all the information creating a point of restoration of the system in order to keep the backup fragmented.
It should be noted that Symantec has renewed its defenses for all types of Windows Server from 2003 to the most recent, which allows better functionality and greater corporate performance.
