The technology and regulations used to safeguard networks and assets that may be accessed across networks against cyberattacks and data loss are referred to as network security. Network security is necessary for businesses of all sizes to safeguard their infrastructure and valuable assets.
To safeguard the network perimeter and its multiple edges, modern network security employs a tiered strategy. Attackers may utilize endpoint devices, data channels, programs, or individuals as entry points into the network. Given the variety of possible threats that businesses must contend with. It is standard practice to implement some network security measures that are intended to deal with specific dangers at certain network and infrastructure levels. A defense-in-depth security approach is what this is known as.
Top 5 Network Security Risks in 2023
Supply Chain Attacks
Attacks on the supply chain take advantage of connections between businesses and outside parties. An attacker may take advantage of this trust connection in the following ways:
- Third-party access
- Trusted external software
- Third-party code
Ransomware
An example of harmful software (malware) is ransomware, which is used to lock information on a targeted machine and show a demand message. Commonly, ransomware programs encrypt data before locking it, then demand payment in bitcoin in exchange for the decryption key.
Criminals frequently purchase ransomware kits on the deep web. These software tools provide attackers the ability to create ransomware with specific functionality and disseminate it to victims in order to demand payment.
Types of Ransomware
Cybercriminals have access to a wide variety of ransomware, each of which functions differently. These are typical examples:
- Scareware
- Encrypting ransomware
- Master boot record ransomware
- Mobile ransomware
API attacks
An application programming interface (API) attack is the malicious use or breach of an API (API). API security is made up of procedures and tools that stop attackers from misusing and abusing APIs. Because APIs are the foundation of contemporary online apps and microservices architectures, hackers target them.
Attacks on APIs include:
- Injection attack
- DoS/DDoS attacks
- Data Exposure
Social Engineering Attacks
To force a target to take a certain action, social engineering assaults use a variety of psychological manipulation strategies, such as deceit and coercion. Below are some typical social engineering techniques:
- Phishing
- Spear phishing
- Smishing
- Vishing
MitM attack
A network assault known as a man-in-the-middle (MitM) attack occurs when an attacker sneaks into a conversation or data transfer between two parties. A successful transfer and impersonation by an attacker of one of the parties.
An attacker may steal data or change the data sent between participants by intercepting the conversation and injecting malicious links, for example. Before it’s too late, neither party is aware of the deception. Users of banking applications, e-commerce platforms, and other platforms that need authentication are frequent targets for MitM attacks.
