How can a user demonstrate that their computer or device is malware free? By periodically performing real time scanning on system for malware that might have been missed by malware shield. 3. What are the steps necessary to establish a malware free computer or device Installing anti-malware software, Scanning and Auditing of system, and removal of malware. 4.
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
Which of the following actions can you NOT perform from the Windows Firewall control panel? (choose all that apply) (C) Create firewall exceptions based on port numbers 6. Which of the following policy modifications would make it harder for intrudes to penetrate user passwords by a brute force attack? (choose all that apply) (A) Increase the value of the Reset Account Login Counter after Policy 7. Connection security rules requires that network traffic allowed through the
IT550 Assignment Unit 1 Kaplan University As the digital age progresses, more and more business is conducted electronically. Symbiotically illegal activities of those that wish to prosper from security vulnerabilities will increase. Cybercrime can be motivated by a number of factors including terrorism. Cyberterrorism is any terrorist act that uses computers as the vehicle for their attack. Cyber terrorists can be motivated to target organizations that will result in the radical’s group to cause the most harm and/or receive the most attention for their party.
Attackers are always looking for devices and software that are newly added to a system and not updated correctly with the security measures in place already. This is the door they look for to get in. A method to avoid such opportunities is to deploy an automated asset inventory discovery tool and use it to build a preliminary asset inventory of systems connected to an organization's public and private network. This will help make the system capable of identifying any new unauthorized devices that are connected to the network within 24 hours, and of alerting or sending e-mail notification to a list of enterprise administrative personnel. Without such a tool in place an attacker will use the unpatched device or software to gain access and manipulate the network how they please.
Port scan is as the name implies, a scan of the open ports on each computer of the network to define which ports are open and what services are running on them. This information can be used to set up an attack on the network by allowing the hacker to bypass vulnerability in the software being run or on any open ports that can be used to gain deeper access to the network. With a port scan the probe sends information to each port on the network and the open ones respond back, this data can be used to determine the easiest way to infiltrate the network. The safest way to defend against this type of probe is using a firewall. Just as in a ping sweep, if you deny access to a port scan requesting information from the network you render them
Many attackers follow a general set of steps in order to gain the permissions necessary to break into a system. The first steps that attackers take is information gathering which gives them an idea about many facets of the system. The facets could include vulnerabilities (such as open ports or an exploit in an old piece of software),
Derek Brunson CISM 3330-03 Plug IT In 6 Discussion Questions 1. | Why is it so important for you to protect your information assets? Can you assume that your organization's MIS department will do it for you? It is important to protect your information assets by behavioral actions and computer-based actions. I can assume that my organization MIS department will do it for me because they would identify issues and problems and promote to employees how to protect their assets that might be vulnerable to theft in the outside world.
Is there a firewall configured on your computer, is your firewall block ing ports, if you turn off the firewall does it resolve your problem? If not move onto the Network Layer; can you ping your default gateway, are your IP settings correct, can you trace a well-known IP/DNS address/URL, and finally has your network adaptor b een assigned an APIPA address? You then move to the data link layer. Is the light lit on your network interface card, is your NIC inserted/installed correctly, is the NIC d isabled in the device 4.4 review 1. The divide-and-conquer
2. Which of the following standalone devices can be found near the Internet edge, with a primary purpose of providing some type of network security between an enterprise or SOHO TCP/IP network and the Internet? (Choose two answers.) a. LAN access point b. IPS c. Analog modem d. Firewall Answer: B, D. A firewall normally sits inline, in the packet-forwarding path, choosing which packets to allow and disallow. An intrusion prevention system (IPS) can sit inline or outside the packet-forwarding path, reporting on complex attacks based on combinations of events.
