Network intrusion detection system

for employees to work in their networking departments. A list of a couple of basic network careers can consist of; Network Specialist, Network Technician, Network Administrator, Network Analyst, Network Manager, Network Engineer, and Network Solutions Architect (tom’sIT PRO, 2014). If you want to further your career after working in one of these mentioned fields, you can specialize in these types of careers; Network Security Specialist, Cloud Networking Architect, Networking Research and…

physical and logical nature, such as disk drive encryption, digital certificates, Transport Layer Security (TLS), and Virtual Private Networks. Recommendation: Implement Full Disk Encryption Full disk encryption is the ability to convert data into unreadable code that can only be deciphered by authorized people. The encryption can include almost everything on the system such as temporary files and swap files. Unlike file encryption, where the decision of which files to encrypt is left up to the…

computer systems and networks are inherently imbued with a number of weaknesses that may compromise their security. Weaknesses take various forms: architectural, procedural, and structural. Programming errors, network errors, operation errors, compatibility errors, and configuration errors are some examples of vulnerabilities. It is supremely useful to identify sources of the vulnerabilities. Ramarkrishnan and Sekar (2002) argue that vulnerabilities stem from interactions among several system…

personal information in computer and mobile devices. For business, McAfee provides the security in web server, emails, and networks; it also prevents the data loss in computer and in cloud server. There are many different ways that McAfee antivirus uses to detect harmful threats in personal devices like signature based, heuristic based, behavioral based, and sandbox detection. In signature based, McAfee antivirus will check all the EXE file and unknown running file for any sign of virus. It…

the organization because it is not prepared for an intrusion of their network. A good fix for this issue is to get the network on the same domain and keep control over all users. Having control over users passwords and access to network locations can help keep a network secure. The other issue that the lab set up is exceptions. Exception are an issue in our lab environment because if a user is trying to ftp and they want to use port 1000 the system wont know how to handle it. This is important…

mobile devices category, there are multiple types of devices – cell phones, smartphones, tablets, Personal Digital Assistant (PDA) devices, and etcetera. In helping the investigators to organize their sources, there are three different events – network intrusion, malware installation, and insider file deletion – can be used to prioritize data sources’ potential usefulness. This paper will discuss 4 major sources of data: log files, hard drives, mobile devices, and social networking websites.…

points before setting up a network and also businesses might get expanded or changed in future. Long term investments should be considered here for future growth as well. So we should have a proper planning before we establish. Number of Users – Number of network users, printers, scanners, servers, data centers and security measures. Types of Equipment – Highly sophisticated equipment that should be capable of handling large networks and flexibility for expanding the networks for future…

to evaluate the connection between hacker and administrator as a two-player zero-sum game. They were able to analyze each state and to model the relationship between the set of system states and the set of states in the stochastic game model. Then, they have calculated the transition rates of the Markov model of the network by solving the game…

several high profile cyber-attacks that have affected various systems across the country and the world. Among these cyber-criminals is the group known as the Shadow Brokers who debuted in August 2016 after claiming to have breached the spy tools of the Equation Group, an elite NSA-linked operation. In April 2017, the Shadow Brokers released what is said to be significant NSA tools which individuals have used to infect computer systems with ransomware. As a result of the Shadow Brokers’ breach,…

crucial to recognize the importance of the Industrial Control Systems (ISC) in our daily life whether it is related to power, transport, water, gas, and other critical infrastructures. Each of these infrastructures is needed at all time and any downtime could be disastrous for the persons and businesses. The following safeguards will help the Western Interconnection power grid as well as any other entity that uses ICS from running a safe system while keeping attackers away on under control. •…
