Guarantees network safety in your company
Introduction
Guarantees network safety in your company Network security is a topic of permanent debate and very concern for companies and in charge of information technology (IT). This is because every day new challenges and cyberamezas emerge. But to calm them down, cybersecurity experts recommend dealing with the matter with a good strategy and knowing the lines of attacks preferred by cybercriminals.
Developing
These negative factors, widely explained in other articles, consist of attacks, malware discharge through insecure navigation, viruses sent by email and internet of things and others. It is worth clarifying that many companies do not find out what these problems have or realize very late. Therefore, in this article we will describe one by one the lines of attacks, basic aspects of network security and the measures that help you guarantee it in your company.
Lines of attacks on networks
According to cybersecurity reports, the following vectors are preferred by cybercriminals to access business networks:
- Business email
This tool is permanently attacked by computer pirates because it has become a business that generates great dividends, of course, illegally. They usually send infected emails with ransomware.
- Internet of things
The Internet of Things (IoT) is also exploited by cybercriminals to achieve their objectives;And companies seem to be so excited with their scope that they tend to neglect the safety and protection of the threats it contains. In the IoT, cybercounts are discovering and exploiting vulnerabilities and creating new methods to break the safety of networks.
- Spyware
It is a form of attack that consists in stealing user information;and by extension, of the company. It is a very effective way to penetrate the safety of networks;appropriate equipment and increase malware infections.
- DDOS attacks
They have the objective of denying the service and are distributed by several attackers. Network security: types, physical and preventive measures on other occasions we have said that the most basic infrastructure of any network is usually composed of devices, means and services. The media and devices are hardware elements, for example, a router or a PC. Services can be any web accommodation.
On the other hand, networks are provided by Internet service providers and the most common connection options are cable, digital subscription (SLD), satellite or telephony by switched connection. Stephen Northcutt, cyber security expert wrote, for many years, about the basic concepts of network safety and set three phases that should be the base frame of reference for the security strategy.
- Protection: You must configure your networks and networks as correctly as possible
- Detection: You must be able to identify when the configuration has changed or if any network traffic indicates a problem
- Reaction: After identifying the problems quickly, answer them and return to a safe state.
It also defined the safety of networks such as the process of taking physical and preventive measures to protect from improper uses, malfunction, modification, destruction or incorrect disclosure, these points.
Similarly, Northcutt said that network safety is implemented through tasks and tools to prevent unauthorized people from entering.
Hardware network security
New threats based on vulnerabilities of operating systems appear daily. Firmware updates not only pursue optimizing their operation, but also correcting possible safety threats and are mandatory at the business level.
This will help you to have a first line of defense in computers or other devices connected to the network. It will also help you prevent possible attacks.
Software network security
Both at the user level and at the business level, software security is one of the most important defense elements.
In the event that a virus manages to enter the network, the antivirus that must be updated will be the containment measure.
On the other hand, if you open an automatic file, the antivirus will block any infection attempt.
Human security
The most important of the factors is the human because many cyber attacks are triggered because an employee has opened an attached infected file in an email.
When this happens, the network security plan must be able to contain the virus so that it is not spread by connected devices.
The review of each and every one of the files that are downloaded from the network with an antivirus or having the information in the cloud must be established as a standard.
The training of employees, on the one hand, and the use of common sense on the other, will help protect the network and devices.
Network security methods
To implement this type of in -depth defense, there are a variety of specialized techniques and network safety types.
- Antivirus: This software helps protect from viruses that arrive by any storage medium or other source.
- Proxy: It is a complement to the firewall that allows access control, traffic registration, performance improvement and communication anonymity.
- Firewalls (firewalls): system that exercises the established security policy, filters the accesses to the network and blocks access to unauthorized people.
- Access control lists (ACL): allow to determine appropriate access permissions to specific users and groups.
- Intruder Prevention System (SPI): It is a system that supports wireless devices to avoid unauthorized access points and other wireless threats.
- Virtual Private Networks (VPN): A secure network extension that is created without the devices being physically connected to each other. When we use a VPN we connect to the Internet services of our supplier and not directly. VPN guarantees data confidentiality.
- Local record encryption: This can be done by means of native Windows encryption or an encryption with solutions to third parties.
- Antimalware: viruses, worms and Trojans can remain inactive in infected machines for days or weeks. Your security effort must be done to prevent infections and also for root malware that is directed to your network. Behavioral analysis: It is about knowing the normal behavior of the network to be able to detect anomalies or infractions as they occur.
Centralized backup copies: in computer networks it is convenient to make centralized and periodic backup copies, which do not occupy too much space. Guarantees extra network security in addition to the typical methods above we describe two systems that will help you guarantee an extra security. Apply appropriate configurations program a system to act and react autonomously to a security event is fundamental. This is achieved through concise adjustments on the attributes and security parameters of any system.
Similarly, appropriate settings must cover all devices involved in the networks: servers, databases, desktop applications and other systems used to transmit information. Experts say that the main security failure occurs when designing and programming systems. In most cases, operability and functionality are weighted above security.
With the purpose of facing this factor, companies must support both suppliers and IT administrators to improve the safety of the operating system. It is also recommended to use white passwords for the server and in the renewable system and passwords every 48 hours. Constantly monitor network security processes
Safety configuration solutions allow to protect conditional vulnerabilities systems. In this sense, all organizations have a variety of network connected devices. Then, Automation of IT safety processes forces to create continuous evaluation routines.
conclusion
As today, any network, however small, is connected to the Internet, it is important to take appropriate prevention measures. On the other hand, we must understand that there is no unique solution that protects itself from a variety of threats;Several security levels are necessary. If one fails, others will do the job. In addition, the software must be constantly updated to protect yourself from emerging threats. On the other hand, it is important to establish cybersecurity strategies to guarantee the maximum protection of networks, data and equipment.
