1. List two examples of system and program threats that may cause damage to a system
-System threat
-Program threat
-System threat: Denial-of-Service (DoS) attacks, wherein an attacker floods a network or system with excessive requests or traffic, causing it to become overwhelmed and unable to function properly.
-Program threat: Malware or viruses, which are malicious programs that can infect and damage a system by stealing or corrupting data, disrupting system operations, or granting unauthorized access to the system.
Sure! Here are two examples each of system threats and program threats that may cause damage to a system:
System Threats:
1. Malware: Malicious software such as viruses, worms, trojans, and ransomware can infect a system and cause various damages like data loss, corruption, and unauthorized access.
2. Denial-of-Service (DoS) Attacks: These attacks overwhelm a system by flooding it with requests or disrupting its network communications, making the system unavailable to legitimate users.
Program Threats:
1. Buffer Overflow: This occurs when a program tries to store more data in a buffer than it can handle, potentially overwriting adjacent memory locations and leading to crashes, security vulnerabilities, or unauthorized access.
2. Logic Bombs: These are pieces of malicious code intentionally inserted into a program that trigger a specific malicious action when certain conditions are met, such as deleting files, modifying data, or launching an attack on the system.
System threats and program threats are two categories of potential risks to computer systems. Here are examples of each:
1. System Threat:
A system threat refers to any action or event that can compromise the security or functionality of a computer system. Some examples of system threats include:
a) Malware attacks: Malware, such as viruses, worms, trojans, ransomware, and spyware, can be injected into a system, causing damage to files, data, or the entire system.
b) Denial-of-Service (DoS) attacks: A DoS attack aims to overwhelm a system with excessive traffic or requests, leading to a system crash or slowdown, rendering it inaccessible to legitimate users.
2. Program Threat:
A program threat focuses on vulnerabilities or flaws within software programs. These can be exploited to gain unauthorized access, steal information, or disrupt system operations. Examples of program threats include:
a) Buffer overflow attacks: This occurs when a program writing data into a fixed-length buffer exceeds its capacity, leading to potential memory corruption and hijacking of the program.
b) SQL injection attacks: If a program allows user input to be directly included in SQL queries without proper sanitization/filtering, attackers can manipulate the input to execute malicious SQL statements, potentially gaining unauthorized access to databases or compromising data.
To mitigate these threats, it is essential to employ various cybersecurity measures such as installing antivirus software, keeping systems and software updated, using firewalls, conducting regular system backups, implementing access controls, and educating users about safe computing practices.
