In this world, it is almost impossible for an organization to run without using digital methods. If an organization tries to limit its digital work, then it will most likely be left behind. The Internet allows businesses to work faster. In contrast, traditional methods were probably safer than these new methods. With every step ahead, there lies a risk. The more an organization is exposed to the digital world, the more they are at risk of network attacks.
This article will talk about what network attacks are, how they can affect an organization, and how effective SOC management can help combat these risks.
What Is a Network Attack?
A network attack is where an organization’s network is attacked by hackers to either ruin organization’s reputation or benefit from the hacked data. After gaining access to the data, the hacker can use it in various illegal ways to put related parties at risk.
The most common types of network attacks are-
- Unauthorized attempts to access systems or data: In this attack, the hacker tries to get into the system using login details. If they are successful, they can access any data they are looking for.
- Phishing attack: In a phishing attack, the attacker masquerades as a reputable person/organization and sends out an email containing a malicious link. When the victim clicks on the link, the malware attacks their system. It either damages the data on the system or steals important data, including login data.
- Malware attack: This attack consists of other types of malicious software attacks as well. In this attack, malware like ransomware, worms, trojans, etc., are installed in the system. This attack aims to damage the network.
- Advanced Persistent Threat (APT): In this attack, hackers generally steal data by hiding in the system and not getting recognized. The attack is carried out by either cybercriminals or nation-states. The attack does not damage the network but can steal sensitive data.
IoCs (Indicators of Compromise)
Data gathered after analyzing a network that suggests malicious activity in a system network is called IoCs. This data suggest that some data has been compromised. IoCs help security operations centers and professionals find malicious infections, breaches in the network, and other threats.
Different Types of Network Attack Methodologies
Attack methodology is used to conduct a successful attack.
- Gather information: In this step, attackers gather as much information as they can get. This data is analyzed and a weak spot is found.
- Vulnerability scanning: Hacker uses vulnerability scanning to figure out a network’s vulnerabilities.
- Footprinting: Hackers also use footprinting to gain more information to find access points in a network.
- Website mirroring: A hacker uses this to copy a website’s content to browse it offline. By mirroring a website, hackers can see the detailed structure of a website.
- Hijacking: A hacker hijacks an online session and takes it over.
- Password stealing: Hackers use password cracking methods like hybrid attacks, brute force attacks, and dictionary attacks to figure out passwords that get access.
How Can SOC Prevent Network Attacks?
Security operations center (SOC) is a team of professionals that help organizations achieve their security goals. These experts use tools and techniques to identify threats as soon as they try to enter the network.
The SOC team includes analysts, incident responders, and subject matter experts (SMEs). SOC keeps themselves updated with the techniques of threat detection and security. They respond to an attack in three stages:
- Detect: It is better to prevent an attack than wait for it and then respond to it. SOC monitors the network and looks for suspicious activities. This way, it prevents them before the hacker does any damage to the network.
- Investigate: After the attack has been identified, an analyst analyses the threat to determine its nature. They also analyze its presence in the entire network to confirm how far it has reached.
- Response: Once an attack has been identified and investigated, experts take action to remove the threat as soon as possible. The aim is to stop them from getting further into the system.
With advanced digitization and intelligent hackers, organizations need SOC management to save them from these attacks. Sometimes attacks are so big that they can bring organizations down. To avoid this, digital industries need candidates who are willing to work hard to save organizations from these malicious network attacks.
EC-Council’s Certified SOC Analyst (CSA) course has been designed to develop candidate’s technical skills. During the course, candidates will receive instructions and tips from specialists that will help them achieve their goals. The candidate will learn to manage various SOC processes and collaborate with CSIRT at the time of need.
