Kostadinov goes on to note that most cyberterrorism actions are generally focused on website sabotage and email blasting. In order to prove that the network breach was a terrorist attack the company would need to provide electronic evidence of these types of information warfare. Information warfare is a term often used interchangeably with cyberterrorism but provides a deeper understanding in the shift of how data has become fundamental to society. As governments, companies and people shift to the use of digital information so have the methods used to attack (Gilmer, 2001). In order to combat this aspect of terrorism, the military have adopted computer forensics as part of their defenses (Vacca & Rudolph, 2011).
Ping Sweep and Port Scan Activities Abstract Ping sweeps and port scans has been a notorious and yet a useful tool for hackers and system administrators alike. This paper will examine some of the possible criminal computer activities that can be executed using these two techniques. Ping sweeps and port scans at times can be a nuisance to system administrators. While describing some of these notorious computer activities, these techniques will also be shown how system administrators can use the to benefit the company. Keywords: port scan, ping sweep Ping Sweep and Port Scans Activities With the evolution of the computer technology, system administrator obviously has had to grow with the technology.
The fact that an attacker can strike remotely makes a Web server an appealing target. Understanding threats to a Web server and being able to identify appropriate countermeasures permits us to anticipate many attacks and prevent the ever-growing numbers of attackers. The main threats to a Web server are: * Profiling * Denial of service * Unauthorized access * Arbitrary code execution * Elevation of privileges * Viruses, worms, and Trojan horses 1) Profiling: Profiling, or host enumeration, is an exploratory process used to gather information about the Web site. An attacker uses this information to attack known weak points. Vulnerabilities: • Unnecessary protocols • Open ports •Web servers providing configuration information in banners Attacks: • Port scans • Ping sweeps • NetBIOS and server message block (SMB) enumeration Countermeasures: Include blocking all unnecessary ports, blocking Internet Control Message Protocol (ICMP) traffic, and disabling unnecessary protocols such as NetBIOS and SMB.
Companies such as this are required not only legally, but ethically to protect the customers’ private information or be held accountable by law. It is also bad practice to allow this sensitive information to be disseminated and stolen by cyber criminals. Since this kind of data must be protected at all costs, certain regulations were put in place so that standards for information security could be monitored. One of these standards is that all personal information is to be encrypted when being sent over the internet and also on the servers. This will make it much harder for the hacker to access the information easily.
They break into our computer for several reasons but mainly to acquire personal information for financial gain, shut down hardware, steal people’s credit information, and destroy data. To protect ourselves from hackers, we should equip our computer with Firewall. This hardware “prevents unauthorized Internet users from accessing private information” (Williams & Sawyer, 2013, p. 361). Identity theft is a serious crime in which thieves steal your name and identity and use to later to make a purchase under your name. Thieves access your personal information by sending out fake e-mail, mining the trash, and stealing your
Internal attacks can be more difficult to find as attackers have the potential to remove any evidence of the attack more easily as they have more knowledge or access rights on the system as opposed to an outside attack. Attacks can be administrated via removable devices such as a USB that could contain some form of malware on it such as a virus. Most internal attacks are conducted by unhappy employees who want to disrupt the organisation by using the knowledge they obtained in the organisation, against the organisation. Additionally, the employee may want to gain access to important data in order to infiltrate and sell the information onto another competing organisation. The
• Imagine you are a CISO of a publically traded company and concerned about security when sending any message traffic over the Internet to your remote sites. Determine the security measures you would consider implementing to mitigate security risks when sending message traffic over the Internet. Explain your reasoning. Teardrop – a mangled packet sent in fragments via overlapping or overloading payloads which could cause the systems as it has in the past with older OS versions. Sequence number – hijacked or interrupted TCP/IP sessions via injected packets that disguises its origination from one of the two computers in a session.
Bystander(s) in cyberbullying are the ones that see the text messages, emails, social media posts, pictures, and videos, but do not forward them onto their contacts. There is also a secondary cyberbully, this person sees the texts, emails, embarrassing photos and/videos, and passes them on to their contacts (Bhat, C.S., Chang, S.H., & Linscott, J.A., 2010). Now I want to look at the risk factors that could be involved with being a bully and a victim. The person being victimized generally may have risk factors like being
Two basic approaches are used in deliberate attacks on computer systems: data tampering and programming attack. Data tampering is a common means of attack that refers to an attack when someone enters false, fabricated or fraudulent data into a computer or changes or deletes existing data. This is the method often used by insiders and fraudsters and is extremely serious because it may not be detected. Programming attacks are popular with computer criminals that use programming techniques to modify other computer programs. For these types of crimes, programming skill and knowledge of the targeted systems are needed.
Through this we get identity taken from us and information of ourselves gets leaked all over the web. Hacks and malicious codes are created to gather your personal information. Anything and Nicholson 2 everything can be exploited beyond your control. This is where cyberbullying comes in. Cyberbullying is bullying via the internet.
