4. LAN-to-WAN • LAN-to-WAN Domain is where the IT Infrastructure links to a Wide Area Network (WAN) and the Internet. Responsible for applying the defined security controls to prevent unauthorized network access 5. WAN • Wide Area Network (WAN) Domain connects remote locations. Manages client’s firewalls and router configurations .The goal is to allow users the most access possible by making sure the data traveling in and out is safe 6.
Layering can be thought of as a medieval castle, or in modern terms, defense in depth. The idea behind it is to make our Keep (data, network infrastructure) safe from the barbarians (hackers, corporate spies). The idea behind layering is to make it hard and un-profitable for the bad guy to breach our network. It’s accomplished by using hardware devices like Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS). Software devices used are; firewalls, Host intrusion Prevention Systems (HIPS), and Antivirus/Malware scanners.
Install, configure, maintain, upgrade, and troubleshoot file, email, and authentication servers, as well as Internet access and other networked services. Assist users with software, hardware, and connectivity issues. Monitor network and systems for performance, security, and other issues. (reference) As a system administrator I am part of an information technology (IT), department, but if you wish you can work for yourself. My love of computers sparked my endeavor into this field.
Assuming the firewall is placed between the internet connection and the Web server, which of the following should be included in the firewall’s configuration so that customers can still reach the Web site? b. Allow incoming TCP-based transmissions to port 80. 2. What of the following is the most secure password?
9/8/2013 SEC280 Case Study Week 1 Case Study: Ping Sweeps and Port Scans Ping sweeps and port scans are not an immediate threat to the company. While it may be used by an attacker to build a profile against the company, it can also be used by an administrator to gather information about the company. Although it is not an immediate threat, it should still be monitored for potential threats because it is a common way for hackers to attempt to break a network. In the following document, more will be discussed about what ping sweeps and port scans are and how they are used to gather information about a company’s network. What is a ping sweep and how does it work?
Case Study For any business ping sweeps and port scans could be a huge security threat if they continue unnoticed. Ping sweeps are performed to find end points on a network. Then a port scan is performed to find an open door into that particular end point or end points. After that anyone can find all kinds of utilities on the internet to exploit these open doors on systems and gain access to important and confidential files on the network. It’s imperative that we not only protect against these types of activities on the network, but that we also conduct them ourselves.
So, governments and ethically operated companies are aware of these limitations. With new technology Individual privacy is one area that has been identified clearly through the application of technologies. Companies can track Internet usage, buying habits and individual movement as well as collect personal information. Companies monitor employees and visitors and collect much additional information in the name of security.
Inefficient security can collapse any online business or operation wherein data is routed over the Internet. The prime objective of Internet security is to lay ground rules and measures to use against attacks over the net. Internet holds a high risk of intrusion and fraudulent activities under its ambit like phishing. Various methods like encryption and steganography have been used to protect data from such malpractices. Internet security will help avoid these frauds online or at least reduce its intensity and prepare organizations to save themselves.
ABSTRACT:In today's growing word cyber security is very necessary because,As technology provides many facility to us it also some effects like security threats and cyber attacks.To protect the data from hanker and the cyber attacks we will require the cyber security. Cyber security is a process to save the networks, computer programs and data from the illegal access or users that aim to access users data for personal uses and benefits.For protection of data many organizations develop a softwares. These software help to protect the data and information. Cyber security playing a big role in developing a technology and other services like internet.we only thing about the ‘cyber security’ whenever we listen about the cyber crimes.This paper describe the cyber security ,cyber
For individuals and organisations these malicious programs can collect authentication data such as account details and passwords which can be later used for cybercrime or hacking. • Spyware: software that covertly transmits data about the activities a user is performing on their system. Spyware can also be used to install additional software, redirect browser searches, change computer settings or disrupt network connections. Typically, spyware is installed during the installation of a piece of free software. • Phishing: is the act of sending emails purportedly from a reputable company in order to trick a user into revealing personal information such as passwords and account details which will be later used for cybercrime.
