Introduction
A lot of security-related vulnerabilities are faced by various telecom operators due to complex infrastructures, privacy concerns, and network problems. This blog contains information related to preventing such problems that can lead to essential data hacking, interrupted services, and privileged essential network.
This blog is divided into seven segments and each segment will explain to you the main agendas related to telecom networks . Let’s have a small look at it
· What is Telecom Network?
· What is Telecom Network Security?
· Why is Telecom Network Security Important?
· What is Cyber Security
· Types of Cyber Security
· Mechanisms used in Telecom Cybersecurity
· Conclusion
Now let us get into the details of all mentioned agendas above and have a better understanding of their relation to them one by one.
What is Telecom Network
In the simplest language, we can say the communication that takes place between two stations which are often common for multiple receiving or transmitting data is called Telecom Network. It covers landlines, mobile phones, VoIP networks, broadcast networks, etc.
Telecom Network Security
Telecom Network Security comprises various structures, protocols, techniques, and measures to provide proper authentication and integrity with confidentiality for private and public networks. Network Security protects your network and data from breaches, intrusions, and other threats. This is a vast and overarching term that describes hardware and software solutions as well as processes or rules and configurations relating to network use, accessibility, and overall threat protection.
Importance of Telecom Network Security
Network security is important because it keeps sensitive data safe from cyber attacks and ensures that the network is usable and can be trusted. Network security management may involve a wide variety of security tools, for both hardware and software. Various Cyber-attacks can be like: -
1. DoS and DDoS Attacks
2. MITM Attacks
3. Phishing Attacks
4. Whale-phishing Attacks
5. Spear-phishing Attacks
What is Cyber Security?
In simple words, Telecom cyber security is the method of defending servers, computers, and other mobile devices from any sought of malicious attacks. Also called electronic information security and can be divided into various categories. Let us understand the seven basic types of cyber security.
7 Types of Cyber Security Threats
Any of Cyber security professional must have an in-depth understanding of the following types of cyber security threats.
1. Malware
Whenever a user clicks any of the attachments that can have a virus or a link which after clicking can lead to the installation of dangerous software that is called malware. These malware can be often named ransomware, worms, viruses, or spyware. This malware are so risky that it can:
· Make the system inoperable by disrupting important parts of the system
· Can lead to the top installation of many other harmful sites
· Hacking of internal data
· Can lead to ransomware
2. Emotet
Saving money in the bank seems like a safe option. But with Emotet malware, your entire life's savings can be wiped off in the blink of an eye. All it requires is for you to click a malicious link, and your bank account will be compromised. Emotet malware is deceptive, fronting genuine files to lure victims.
The Cybersecurity and Infrastructure Security Agency (CISA) describes Emotet as “an advanced, modular banking Trojan that primarily functions as a downloader or dropper of other banking Trojans. Emotet continues to be among the most costly and destructive malware.”
3. Denial of Service
A Denial of Service (DOS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic or sending it information that triggers a crash. This is a security attacker that creates a malicious website that doesn’t allow a network to respond to requests.
Cyber attackers often use a flood attack to disrupt the “handshake” process and carry out a DoS. To mitigate the risk of a DDoS threat, telecom operators can implement web application firewall technology or content distribution networks to filter out unauthorized traffic. Another common solution is to reroute DDoS-generated traffic through a dedicated “scrubbing center,” which removes malicious traffic and allows normal traffic to flow forward.
4. Man in the Middle
A man-in-the-middle (MITM) attack occurs when an unwanted element or a hacker interrupts the traffic through the two-party transaction. They often steal the data by using an unsecured wi-fi network and then use suspicious malware to install obnoxious software maliciously to utilize the same data for malicious activities.
5. Phishing
Phishing attacks use fake communication, such as an email, to trick the receiver into opening it and carrying out the instructions inside, such as providing a credit card number. According to Cisco reports Phishing attacks use fake communication. They say, “The goal is to steal sensitive data like credit card and login information or to install malware on the victim’s machine,” by tricking them to open as per instructions and insert their credit card number.
6. SQL Injection
A server releases a Structured Query Language (SQL) injection, a type of cyber-attack that results from inserting malicious code into a server that uses SQL. When infected, the server releases information. Submitting the malicious code can be as simple as entering it into a vulnerable website search box.
7. Password Attacks
Often beginning from outright guessing to accessing a password database the attackers leave no stone unturned to access the most important information of the business. Social engineering is a type of password attack that Data Insider defines as “a strategy cyber attackers use that relies heavily on human interaction and often involves tricking people into breaking standard security practices.”
Security Gen is a prevention technique for Cyber Attack
Security Gen’s latest Artificial Cybersecurity Expert (ACE) SaaS model is designed to help reinforce measures to control signaling threats and ensure heightened security. ACE enables independent testing of signaling networks, without having to rely on local teams. Once enabled, ACE will conduct a thorough security assessment of your signaling premises, create a report that highlights critical issues, and delivers it to the relevant teams. In case of additional assistance is needed, MNOs can connect with our security experts to seek in-person consultations.
ACE as a service helps test the MNO networks on various roaming protocols like SS7 MAP, SS7 CAMEL, Diameter, and GTP-C.
