What is Cyber Security Approaches for Threat Detection and Remediation

Cybersecurity refers to the protection of computers, servers, mobile devices electronic systems, networks, and data from viruses and malicious attacks. This term can also be called information technology security, or electronic information security.

Importance of Cyber Security

Much vital data is stored and collected by many organizations, including the government, corporate houses, and medical organizations. A considerable fraction of that data could be classified as sensitive information. It doesn’t matter if it is intellectual property, financial information, or any other type of data that could lead to unfavorable outcomes. In the course of their business, organizations transfer sensitive data over networks and to other devices. Cybersecurity is the discipline that protects this information. It also describes the systems and processes used to store or process it.

 Different Types of Cyber Threats

Phishing

Phishing is a popular type of cyber-attack. Phishing is the act of sending fake emails that appear to be from trusted sources. It is designed to steal sensitive data such as login information and bank card numbers.

Ransomware

Ransomware is a type of malicious software. This malware is used to steal money by blocking files and computer system access until a ransom is paid.

Malware

Malware is software that’s intentionally designed to gain unauthorized access to your computer or cause damage to it. Malware includes computer viruses, trojan horses, worms and spyware, adware, rogue applications, wiper, and scareware

Elements of Cyber Security

Every organization must coordinate its efforts across the entire information system in order to achieve significant cybersecurity. All of these elements are part of cybersecurity.

  • Network security: It is the process of protecting your network from unwanted users, attacks, or intrusions.
  • Application security: To ensure that programs are safe from intruders, they must be updated and tested regularly. Security must be implemented at the design stage before any program or device can be deployed.
  • Operational security: Refers to the processes and decisions that are used to manage and protect data assets. Operational security covers accessing networks and procedures that control how and where data can be stored and shared.
  • End-user education: People are the most important cybersecurity factor. If a person fails to observe good security practices, he can accidentally release a virus into an otherwise safe system. It is important to instruct users to delete all suspicious email attachments and to stop plugging in unidentified USB drives.
  • Databank and infrastructure security: It is important to protect devices that contain databases and other equipment in order to maintain consistency in the work process.

Cyber Security Approaches to Intrusion Detection & Prevention

There are two types of network protection systems: Intrusion Prevention Systems and Intrusion Detection Systems. IDS/IPS compares network packages to a cyber threat database that already contains known signatures of cyberattacks. It then ensigns matching packets to promote cybersecurity services.

An Intrusion Detection System is a program that monitors network traffic and alerts the system if it is detected. An administrator is usually notified of any malicious acts or violations. A security information and events management (SIEM), the system is used to centralize such reports. A SIEM framework is a combination of data from multiple sources and uses alert filtering techniques in order to distinguish between false alarms and malicious ones.

Intrusion Prevention System (IPS)

Intrusion Prevention System also known as Intrusion Detection and Prevention System is a network protection program that monitors network operations for malicious activity. It can also prevent packet transmission depending upon the type of attack it detects. This aids in the prevention of an attack.

Intrusion Detection Systems (IDS) are being investigated as a complement to Intrusion prevention systems. Both IPS and IDS monitor the network traffic for malicious activity.

Six fundamental approaches are available for Intrusion Detection and Prevention. Some methods can be executed within different software packages, while others are strategies that an organization uses to decrease the chance of intrusion.

These are the approaches to intrusion detection and prevention:

1. Pre-emptive Blocking

It’s also known as Banishment Vigilance. It prevents intrusions from happening before they occur.

This is done by notifying the administrator of any impending attacks, and then blocking the IP address or user responsible. A software system will alert the administrator whenever suspicious activity occurs. Administrators then decide whether to block these unwanted activities. Software that blocks addresses it considers suspicious can lead to blocking legitimate users. This type of approach should not be used as a whole strategy for intrusion detection.

2. Anomaly Detection

This method uses existing software to detect intrusion attempts and notify the administrator. It is very simple. The system first looks for abnormal activities or activity that is not consistent with the established pattern. The system then compares the activities observed with the profile’s expected behavior.

Any untoward activity is considered an anomaly and is logged. This is often referred to as a “traceback detection” or “traceback process.”

3. Threshold Monitoring

Threshold monitoring monitors behavior and determines if they are being met. You could limit the number of login attempts that fail or control the time it takes to connect and how much data is downloaded. This is how the system defines acceptable behavior.

4. Resource Profiling

This method aims to create a historical usage profile and measure the system-wide resource use. Abnormal readings could indicate that there is an illegal activity. It can be difficult to interpret changes in system usage.

5. User/Group Work Profiling

This approach allows the IDS to preserve individual work profiles for users and groups. These profiles must be adhered to by both users and groups. Users can also update their expected work profiles automatically if they change their activities. This can be either short-term or long-term, depending on the system. Short-term profiles are those that capture recent shifts in work patterns. Long-term profiles last for a longer time.

Cyber Security Trends

All businesses, large and small, have embraced digital technology. This means that they can rely on computers to manage their day-to-day operations. Cybersecurity is a key goal in order to protect data from any online attack or unauthorized access. These are the top cybersecurity trends for 2021.

1. Rise of Automotive Hacking

In 2021, the most important cybersecurity trend will be automotive hacking. Autonomous software is embedded in modern vehicles, allowing for seamless connectivity to assist drivers with everything from engine timing, cruise control, door lock, and even airbags. These vehicles can communicate via Bluetooth and WiFi, which makes them vulnerable to hackers.

2. Integrating AI and Cyber Security

This technology, which combines machine learning and AI, has made huge changes in cybersecurity services. AI is a key component in many areas, including building automated security systems, natural language processing, face detection, and computerized threat detection. It is also used to create smart malware and attacks that bypass the most recent security protocols for controlling data.

3. Mobile is the New Target

More threats are lurking in our emails, photos, financial transactions, messages, and emails. In 2021, cybersecurity trends may be captivated by smartphone viruses and malware.

4. IoT and 5G Network: A New Era of Technology and Risks

The 5G networks, which are set to be globally rolled out in the near future, could be one of the new cybersecurity technologies. The Internet of Things (IoT), which will bring a new era of interconnectivity, could be a reality. This transmission between multiple devices opens them up to vulnerability from outside influence, attacks, or an unknown software bug. Even Google Chrome, the most popular browser in the world, has serious flaws. Each step in the 5G network could bring a multitude of network attacks that we may not be aware of.

5. Automation and Integration

Automation is essential to provide more control over data, as the volume of data is increasing every day. Professionals and engineers are required to offer quick and skilled solutions in modern active work. Automation is now more valuable than ever. It is also difficult to secure large and complex web applications. This makes automation as well as cybersecurity an important part of the software development process.

6. Cloud is Potentially Vulnerable

Every organization now has cloud information. Security measures must be regularly regulated and updated in order to prevent data leaks. Even though cloud applications like Microsoft and Google are well-organized with security, the problem is on the user’s side. It can lead to inaccurate errors, malicious software, and even phishing attacks.

7. Data Breaches: Prime target

Protecting digital data, whether it’s for an individual or an organization, is the main goal. Hackers can easily access personal information by gaining access to any flaws or bugs in the software or system browser.

8. Insider Threats

Data breaches can still be caused by human error. A bad day or planned loophole could bring down an entire organization that has millions of stolen data. It is important to raise awareness on the premises to ensure data security in every possible way.
