Take care of server security It is essential to stay protected from cyberattacks, which have become increasingly common.
Moreover, there has been a considerable increase in the number of cases, and they are directed at residences, businesses, government agencies, and other types of users.
Therefore, the need for protection increases, especially when we talk about servers. But when it comes to them, many people have doubts about how to do it.
However, server security requires attention from companies, since it stores all business information, which is often confidential and cannot be lost.
With the arrival of the new General Data Protection Law, it is even more important for companies to protect customer information so that it is not compromised in any way.
They are also on the servers, so this is yet another reason for organizations to take care of this security. But not all know how to do this or have the appropriate personnel, and end up taking risks.
With that in mind, in this article, we'll show you which tools and practices to use to maintain server security, as well as give you some more tips. Check it out!
Why keep servers protected?
Cybercrimes have become commonplace in recent years, leading thousands of companies to seek more effective ways to protect their servers and the information contained within them.
These attacks have evolved and now use different methods, such as artificial intelligence and machine learning in malicious actions, which make companies' operating systems more vulnerable.
Furthermore, the highly digitized and interconnected infrastructure used by corporations facilitates hacker activity.
Added to this is the lack of security, which further aggravates the situation. And in the midst of all this are the employees, who, due to a lack of guidance, have a routine that enables such actions and makes the work of the IT department more complicated.
To avoid risks, a residential security companyFor example, the company instructs its employees not to open emails with suspicious content or leave the system open when they are away from their workstations.
However, there is an even more important action: maintaining server security, since it stores sensitive data throughout its infrastructure.
A single attack can gain access to different computers, targeting them in a programmed way, which overloads the server until it is brought down.
When this happens, the user themselves is unaware that their computer contributed to the disaster. All the criminal needs to do is activate a program that was installed on the machine to gain access to all the information they want.
Keeping the server protected helps mitigate its vulnerability, which is associated with actions such as:
- Strict access policy;
- Use strong passwords;
- Use of antivirus software;
- Software update.
These and many other actions are necessary, so in the next topic, we will show how... insurance companies, and many others, can keep your server protected.
Important safety tools and practices
Server applications cannot function without guaranteed security, as this could have serious consequences.
However, some actions can prevent them, namely:
SSH keys
This refers to a pair of cryptographic keys used to authenticate to an SSH server. They function as an alternative to password logins.
Before authentication, two keys are created: one public and one private. The private key must be kept secret by the user, while the public key can be shared.
To configure SSH key authentication, the user's public key must be placed on the server in a special directory.
When connecting to the server, the user will be asked to provide proof that they possess the private key, thus proving ownership of it. This allows them to connect to the server without using a password.
VPNs and private networks
Private networks are available only to specific servers and users, such as in a physiotherapy clinic which makes use of this technology, and this works through a wide network of data centers.
Using a VPN, it's possible to create more secure connections between remote computers, with a connection equivalent to a local private network.
It's a way for the organization to configure services as if they were on a private network, connecting remote servers via secure connections.
SSL/TLS encryption
Public key infrastructure, or PKI, is a system designed to create, manage, and validate certificates that identify individuals and encrypt communication.
SSL/TLS certificates authenticate different entities with each other, and after authentication, they can encrypt communication between computers within a network. factoring company, for example.
Intrusion detection system
This method, also known as IDS, is software that monitors a network or system for unauthorized activity.
There are many host-based IDS implementations that use file auditing as a way to verify if the system has undergone changes.
It is also possible to use file auditing, which compares the current system to file records and their characteristics within the system.
This is how changes to the system are detected, which may have been authorized at some point.
Isolated execution environments
It is a method in which the individual components run in their own dedicated space.
To achieve this, it is necessary to separate the discrete application components within the servers, or to configure the services so that they can operate in chroot or container environments.
However, the level of isolation will depend on the reality of the available infrastructure or the application requirements.
Now that you know how organizations, such as a concierge companyThese measures can make the security of your servers more effective; in the next section, we'll show you how to maintain their security. Stay tuned!
Tips for maintaining server security
No system is secure all the time; therefore, it is necessary to invest in improvements to increase security.
So, among the best ways to do this, we have:
First-level security
One of the fastest-growing forms of internet crime is known as Crime as a Service (CaaS). These are malware programs created and made available on sales platforms, allowing people with little technical knowledge to carry out attacks.
In other words, it's a type of marketing that provides tools for criminals to operate, and it's becoming increasingly common.
So, antivirus programs, firewalls, and VPNs themselves are basic security systems that companies, such as an office, use. specialized IT accountingThey need to have it.
Professional versions are available, which should always be up-to-date and configured to meet the demands of the IT infrastructure.
Updated and disconnected backups
Backup management is a simple and effective action, but unfortunately, it doesn't receive the attention it deserves from corporations.
Security is not guaranteed if data copies remain connected to the network, meaning they can be accessed by ransomware.
Every backup performed needs to be maintained independently and constantly updated. If they are truly secure, a accounting Office It can reduce the risk of damage caused by data breaches or data compromise.
Information security policy
Developing an information security policy is essential, as it is the most important part of a secure system.
A good IT infrastructure requires actions related to physical and digital access to servers. Therefore, it is necessary, for example, to install security doors and digital access barriers.
They all need to be controlled by a system that operates hierarchically for access, defined by the managers.
However, it is necessary that a company's security policy real estate consortiumFor example, just like all the others, it should be aligned with the organizational culture.
Only in this way is it possible to guarantee the constant protection of physical and digital assets. It is also necessary to invest in an action plan for real-life attack situations.
Even though it's undesirable, every organization should have a specific protocol to guide professionals through critical moments. After all, even if it seems unlikely, it can happen at any time.
Conclusion
Taking good care of server security is essential to keep important data and information always protected from criminals. They can use it for various purposes, which can cause significant damage to the corporation.
This protection depends on the tools and practices we've shown here, but also on continuous improvement actions that you've also learned about in this text.
By following our tips, your company's server will always be secure, and your company will be prepared to handle situations that require specific precautions.
