# A Secured Intrusion Detection System for Mobile Edge Computing
## 3 Types of Attacks on Mobile Edge Computing  
_Routing Information Protocol (RIP)_[24] is a dynamic routing protocol commonly used within computer networks to facilitate the exchange of routing information between routers. While RIP is a widely adopted protocol, its simplicity can make it vulnerable to various types of attacks. _Route Flapping:_ In this attack [25], a malicious actor advertises false or poisoned routing information to routers in the network. The attacker may advertise unreachable or undesirable routes, leading routers to make incorrect routing decisions. Route poisoning can disrupt normal network operations by causing routers to forward traffic along incorrect paths, leading to connectivity issues and potential data interception. Route flapping involves continuously and rapidly advertising and withdrawing routes. This activity can consume network resources and cause instability in the routing tables of neighboring routers. Route flapping can lead to network congestion, increased bandwidth usage, and potential service disruptions as routers struggle to adapt to frequent changes in routing information. _Denial of Service (DoS):_ A Denial-of-Service attack [26] on RIP can involve overwhelming the RIP routers with excessive traffic or malformed packets, causing them to become unresponsive or leading to degraded performance. A successful DoS attack can result in a loss of network connectivity, rendering the RIP routers incapable of providing routing services and potentially disrupting overall network functionality. _Spoofing Attacks:_[27] Malicious entities may attempt to spoof RIP packets by forging the source address to appear as a trusted router within the network. This can allow the attacker to inject false routing information. Spoofed RIP packets can mislead routers into accepting unauthorized routing updates, potentially leading to traffic interception, rerouting, or other security compromises. Table 1 presents an overview of all these attacks as follows. \begin{table}
\begin{tabular}{c c} \hline
**Attack** & **Description** \\ \hline Route Flapping & Route flapping is a network instability issue where a route alternates between available and unavailable states in a rapid and repetitive manner. \\ \hline Denial of Service (DoS) & A Denial-of-Service attack aims to disrupt the normal functioning of a system or network by overwhelming it with a flood of traffic, rendering it incapable of providing routing services. \\ \hline Spoofing Attacks & Spoofing attacks involve the impersonation of a legitimate entity or source by falsifying information. \\ \hline Unauthorized Access & Unauthorized access refers to gaining entry or privileges to a system or network without proper authorization. Attackers exploit vulnerabilities to bypass security mechanisms and access sensitive information or resources. \\ \hline Malware Injection Attack & A malware injection attack involves inserting malicious code or software into a system or application. This code can compromise the integrity of the system, steal sensitive information, or perform unauthorized actions. \\ \hline \end{tabular}

Table 1: Overview of possible attacks for IDS in mobile edge computing. _Unauthorized Access:_ Unauthorized access [28] to routers running RIP can result in an attacker gaining control over the routing tables and configurations. This can lead to the manipulation of routing information. Unauthorized access allows attackers to modify routing tables, redirect traffic, or cause network outages, compromising the overall integrity and security of the network. _Malware Injection Attack:_ A malware injection attack [29; 30; 31; 32], also known as a code injection attack, is a type of cybersecurity threat where malicious code is inserted into a legitimate application or system with the intent of compromising its functionality, stealing sensitive information, or gaining unauthorized access.
