The internet has taken control of our lives. Every time we depend on the network between computers even with the Internet we can make it easier for almost all. Online essay writing service makes our academic process easier, online ticketing makes it easy for us to book tickets and much more. But there are things that are often forgotten by Internet users, data security!
In general terms, data security refers to digital privacy protection measures that are applied to prevent unauthorized access to data, which can be found in computers, databases, websites, etc. Data security also protects data from possible corruption.
What is data security?
Data security, also known as information security or information security, is an essential aspect of IT in organizations of any size and type. This is an aspect that has to do with the protection of data against unauthorized access and to protect them from possible corruption throughout their life cycle. Data security includes concepts such as data encryption, tokenization and key management practices that help protect data in all applications and platforms of an organization. Today, organizations around the world invest heavily in information technology related to cyberdefense in order to protect their critical assets: their brand, intellectual capital and customer information.
Some concepts you should know
Data security is a very important issue that affects almost all of us. Every time there are more technological products that in one way or another must be taken into account for security issues and that are being introduced in our daily life, from smartwatches to vehicles without driver. The Internet of Things (IoT) era has arrived and, of course, the IoT-related hacks. All these connected devices create new “conversations” between devices, interfaces, private infrastructures and the cloud, which in turn creates more opportunities for hackers to listen. All this has driven a demand for solutions and data security experts who are able to build stronger and less vulnerable networks.
Data security engineering
Security engineers aim to protect the network from threats from its inception until they are reliable and secure. Security engineers design systems that protect the right things in the right way. If the goal of a software engineer is to ensure that things happen, the goal of the security engineer is to ensure that (bad) things do not happen by designing, implementing and testing complete and secure systems.
Encryption
If data security engineering protects the network and other physical assets such as servers, computers and databases, encryption protects the data and real files stored in them or traveling between them through the Internet. Encryption strategies are crucial for any company that uses the cloud and are an excellent way to protect hard drives, data and files that are in transit through email, in browsers or on the way to the cloud.
Intrusion detection and response to a security breach
If suspicious-looking actions occur on the network, such as someone or something trying to enter, intrusion detection will be activated. Network Intrusion Detection Systems (NIDS) continuously and passively monitor network traffic for behavior that appears illicit or anomalous and mark it for review. NIDS not only blocks that traffic, they also collect information about it and alert network administrators.
Firewall
How to keep unwanted visitors and malicious software out of the network? When you are connected to the Internet, a good way to ensure that only the right people and files are receiving our data is through firewalls: software or hardware designed with a set of rules to block access to the network of unauthorized users. They are excellent lines of defense to prevent data interception and block malware trying to enter the network, and also prevent important information from leaving, such as passwords or confidential data. You can test the security of your computer with a firewall tester online.
Vulnerability scan
Hackers often analyze networks actively or passively in search of holes and vulnerabilities. Data security analysts and vulnerability assessment professionals are key elements in identifying possible holes and closing them. The security analysis software is used to exploit any vulnerability of a computer, network or communications infrastructure, prioritizing and addressing each of them with data security plans that protect, detect and react.
Intrusion tests
Vulnerability analysis (which identifies potential threats) may also include deliberately investigating a network or system to detect failures or make intrusion tests. It is an excellent way to identify vulnerabilities ahead of time and design a plan to solve them. If there are operating system failures, problems with breaches, code for certain applications or other similar problems, a network administrator expert in intrusion testing can help you locate these problems and apply patches so that you are less likely to have an attack.
