 What is cybersecurity?





Cybersecurity is the protection of computers, servers, mobile devices, electronic systems, networks and data from malicious attacks. Also known as IT security or electronic information security. The term applies in many different contexts, from business to mobile computing, and can be divided into several general categories.

  • · Network security is the protection of computer networks from intruders (either targeted attackers or opportunistic malware).

  • · Application security focuses on protecting software and devices from threats. A compromised application may allow access to the data it was designed to protect. Successful security starts at the design stage, long before any program or device is deployed.

  • · Information security protects the integrity and confidentiality of data at rest and in transit.

  • · Operational security consists of processes and decisions for handling and protecting data stocks. The privileges that users have when accessing a network and the procedures that determine how and where data can be stored or shared all fall under this umbrella term.

  • · Disaster recovery and business continuity define how an organization responds to cybersecurity incidents and other events that cause loss of operations or data. A disaster recovery policy determines how an organization can restore its operations and information to the same operational capabilities as before the event. Business continuity is the plan that an organization resorts to when trying to operate without specific resources.

  • End-user training addresses the most unpredictable factor in cybersecurity: people. Viruses can inadvertently infiltrate secure systems if security best practices are not followed. Teaching users to remove suspicious email attachments, not plugging in unidentified girlfriend USB drives, and a variety of other important lessons is critical to organizational security.

Why is cybersecurity important ?

The increasing number of users, devices, and programs in modern enterprises, coupled with the increasing flow of data, many of which are sensitive or sensitive, makes cybersecurity an ever-increasing importance. The growing volume and sophistication of cyber attackers and their attack techniques exacerbates the problem.

What are the benefits of cybersecurity ?

  • Business protection against cyberattacks and data breaches. 

  • protection of data and networks.

  • Prevention of unauthorized user access.

  • Improved recovery time after a violation.

  • protection of end users and endpoints.

  • Regulatory Compliance.

  • Business Continuity.

  • Increased confidence in the company’s reputation and trust in its developers, partners, customers, stakeholders and employees.





Types of the Cyber Security threats 

  1. Malware :

  Malware is harmful software such as spyware, ransomware, viruses, and worms. When users click on malicious links or attachments, it activates malware and installs dangerous software.

  • Block access to critical network components (ransomware)

  • Install additional malicious software

  • Obtain information covertly by transferring data from your hard drive (spyware)

  • Individual components and render the system inoperable

  1. Emotet :

The Cybersecurity and Infrastructure Security Agency (CISA) describes Emotet as “a highly modular banking Trojan that primarily acts as a downloader or dropper for other banking Trojans. It is one of the most costly and destructive malware out there.”

  1. Denial of service :

A denial of service (DoS) is a type of cyberattack that floods a computer or network so that it is unable to respond to requests. Distributed DoS (DDoS) does the same thing, but the attack comes from a computer network. Cyber ​​attackers often use flood attacks to disrupt the “handshake” process and perform a DoS. Several other techniques are available. Some cyber attackers take advantage of network downtime to launch another attack. According to Jeff Melnick of Netwrix, an information technology security software company, botnets are a form of DDoS in which millions of systems can be infected with malware and controlled by hackers. Botnets, sometimes called zombie systems, target and overwhelm a target’s processing power. Botnets exist in different geographical locations and are difficult to track.

  1. Man in the middle :

  A man-in-the-middle (MITM) attack occurs when a hacker breaks into a two-party transaction. According to Cisco, data can be filtered and stolen after traffic is interrupted. MITM attacks often occur when visitors are using unsecured public Wi-Fi networks. Attackers get between your visitors and your network, use malware to install software, and misuse your data.

  1. Phishing :

Phishing attacks use fake communications. B. An email asking the recipient to open the email and follow the instructions provided. B. Specifying a credit card number. “The aim is to steal sensitive data such as his credit cards and login information, as well as install malware on the victim’s computer,” he reports Cisco.

  1. SQL Injection :

Structured Query Language (SQL) injection is a type of cyberattack created by injecting malicious code into a server that uses SQL. Once infected, the server publishes information. Malicious code can be submitted by simply typing into the search box of a vulnerable website.

  1. Password attack :

With good passwords, cyber attackers can access a wealth of information. Social engineering is a type of password attack defined by Data Insider. Other types of password attacks include access to password databases and outright guessing.


How is automation used in cybersecurity?

Automation has become an integral part of protecting organizations against the increasing number and complexity of cyber threats. Deploying artificial intelligence (AI) and machine learning into data-flow-heavy areas could help improve cybersecurity in three main categories:

  • Threat detection. AI platforms can analyze data to detect known threats and predict emerging threats.

  • Threat Response. The AI ​​Platform also creates safeguards and automatically enforces them.

  • Human Augmentation. Security professionals are often overwhelmed with alerts and repetitive tasks. By automatically triaging low-risk alerts and automating big data analysis and other repetitive tasks, AI can help eliminate alert fatigue and free up humans for more demanding tasks.

  • Other benefits of cybersecurity automation include attack classification, malware classification, traffic analysis, and compliance analysis.
