Security

IT security is the protection of information, particularly information processing. IT security is designed to keep unauthorized third parties from tampering with data and systems. This means that socio-technical systems are safeguarded from damage and dangers. Not only does this refer to information and data, but also to actual data centers or cloud services.

The effects of cyber-attacks demonstrate, through a variety of occurrences, that IT security is essential in today's environment. If confidentiality, integrity, or availability are not satisfied, it can have a disastrous effect on a company's profitability.

Why is there a need for IT Security?

Cybercrime may pose the greatest threat to your company, its data, and its brand reputation. And that threat is changing and growing tremendously almost every day. Having outsourced help to ensure complete cyber security for your online and offline data can save you from a huge financial and work hour loss. While ensuring IT security can be costly, the expense of a big breach is significantly greater. Large breaches might put a small business's health at risk. To gain control of a situation during or after an occurrence, IT security professionals might use an incident response plan as a risk management tool.

Types of Cyber Attacks

Advanced Persistent Threats (APTs) - Hackers devote a significant amount of time, effort, and resources to breaking into a system to damage the entire network.
Phishing - An attempt to reveal confidential data.
Malware - Any type of malicious software that damages the system.
DDoS Attacks - Bots cause a large number of requests to paralyze the victim’s server.

Objective of IT Security

Information Confidentiality
IT Security confidentiality means that data is only available to authorized individuals. The transit of data is another critical aspect of information secrecy. This should be encrypted at all times, whether symmetrically or asymmetrically. This means that unauthorized individuals will be unable to access the contents.

Integrity of Information
The information's integrity should be seen to ensure that the contents and data are always complete and correct. As a result, the systems must collaborate for their own benefit. To be able to use data, it must not be altered through a sales or processing procedure. As a result, it is also vital to mention that the authoritative Dritte has no way of accessing (part of) the data.

Information Availability
Ensuring the availability of the relevant information entails ensuring that data processing within the systems occurs smoothly. The data must be retrievable correctly and at the desired time. This implies that computer systems must be safeguarded against failure.

Areas that are covered by IT Security

Endpoint Protection

All important end devices, such as PCs, notebook computers, tablets, and cell phones, must be safeguarded. This includes the apps and operating systems that go with them. Endpoint security is concerned with safeguarding everything that travels via the enterprise network and connects to the Internet.

Cloud and Internet Security

IT security takes on new relevance when instant information is disseminated on the Internet or communicated via email. The threat of cyber attacks on systems, information, and data is increasing. From then on, it is also true that users or their data are secured. Because users' digital identities leave imprints as soon as they move throughout the World Wide Web.

User Safety

The IT department should be very careful to counteract security threats by employees. The risk exists whether through an application on a personal smart phone or through updates on a laptop. If an email attachment is too large, it should not be sent to your personal email address right away. The IT department must raise user awareness so that every employee in the firm is aware of the importance of IT security.

SIEM to mitigate DDoS

SIEM (security information and event management) provides real-time event monitoring and analysis, as well as tracking and logging of security data for compliance or auditing purposes. SIEM is capable of much more than just incident detection and prevention. It detects flaws and bad practices that could lead to problems, as well as hostile activities before it escalates into a full-fledged attack. Persistent malware makes an effort to be undetectable. It slows down the rate at which it infiltrates information in order to avoid triggering alarms. SIEM can detect anomalous account usage patterns.
