Threat Detection

Any person or business that connects to the internet is at risk of potential cybersecurity threats. The key to stopping threats is knowing how to recognize them.

What is threat detection?

Threat detection is the process of identifying cyber attacks trying to enter a machine or network. Threats are any actor or technology that has the potential to cause harm to a system. They are not the actual attack, just the possibility of one. Threat detection uses previously identified intrusion signatures and network traffic anomalies that deviate from normal baselines of behavior to identify threats so they can be stopped before being exploited.

What information is at risk?

Most attacks are aimed at stealing information that can be used for monetary gain. This data can come in multiple forms.

Intellectual property

In order to compete with big players in their market, some organizations may take a malicious route. They may hire attackers to steal intellectual property and trade secrets to bolster their own products and services.

User credentials

An easy way for hackers to gain access to a network is by stealing user credentials. In these cases, they’re not after an authorized user’s personally identifiable information (PII). Instead, bad actors seek network logins and passwords as a doorway to more sensitive resources. With the common lack of strong passwords and the frequency of scamming, stealing user credentials are often low-hanging fruit.

Personally identifiable information (PII)

Personally identifiable information (PII), on the other hand, specifically impacts individuals. PII includes information that can be used for identity theft, such as social security numbers and bank account information. The goal of identity theft is often to open accounts in usernames and make purchases on their behalf.

Types of threats

Organizations of every size face a wide variety of threats. Threat detection identifies and analyzes these types of threats so that security teams can formulate strategies to mitigate risk. Here are some of the most common types.

Malware

Malware is malicious software that infects a machine or network. It can come in multiple forms, including viruses, trojan horses, ransomware and spyware.  Malware can cause a variety of major issues, such as interrupting or disabling services, stealing sensitive information, taking control of applications and breaking down network infrastructure.

Phishing

Phishing is a form of social engineering attack that aims to trick users into revealing personal data, such as PII or credentials. The most common forms of phishing are through electronic communications, such as emails or websites requesting information.

DDoS

DDoS attacks flood servers and networks with traffic that make resources and websites unavailable. These attackers infect machines with malware so they can be controlled remotely. Each device is then turned into a bot, or zombie, which is instructed to send requests to IP addresses to cause an overwhelming spike in traffic that overloads a network.

Ransoms

Some attackers take a more aggressive approach and will hold information or resources hostage until they’re paid a ransom. One common method is to encrypt an organization’s information and hold the encryption key hostage. They may also use distributed denial-of-service (DDoS) attacks to interrupt the availability of resources until they receive a ransom.

Threat detection tools

Due to the importance of threat detection, many cybersecurity products offer threat detection as a feature. Some of the most popular solutions with threat detection include:

Threat detection and response (TDR)

Threat detection is essential to maintaining a strong security posture but it’s only the first step. Response must follow to remediate the identified threats. The majority of tools that offer threat detection also offer response.

These threat intelligence platforms can automatically contain and block threats, as well as automatically implement patches. Others may offer the ability to prioritize risks and offer guidance to security teams to help them remediate the most high-risk threats first.
