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
Malicious damage: Examples can be Viruses, Worms or Trojans a. Internal attacks come from within the organisation by disaffected staff. Individuals or a group have authorised access and privileges to the organisations network. They may use their knowledge on the organisations network to exploit or interrupt its functions. 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.
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.
I would implement firewalls, cryptography, antispyware, antivirus, and content filtering. These will be installed in various levels of our network infrastructure including, our mail servers, gateways, laptops and desktops. When these security technologies are in place a threat may be able to bypass on level of security but will be detected and eradicated at another. Layering our security in this manner will mitigate the risks of an employee disabling their protection on the workstations. Our mail servers which send, receive and store emails must be secured as well.
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. Cyberterrorists use the internet to spread propaganda and enlist new members and use DoS/DDoS attacks to cause disruption to companies that represent actions against their belief’s (Vacca & Rudolph, 2011). Cyber terrorists can also steal information to be used for self-serving strategic purposes. Kostadinov (2012) makes the distinction between cybercrime and cyberterrorism in that the latter should resemble terrorist attacks via traditional methods but perpetrated virtually. Kostadinov goes on to note that most cyberterrorism actions are generally focused on website sabotage and email blasting.
Which of the following account lockout policy modifications could you make to ensure that user passwords cannot be intercepted by analyzing captured packets? (D) Disable the Store Passwords Using Reversible Encryption policy 2. Which of the following mechanisms is most often used in firewall rules to allow traffic on to the network? (D) Port numbers 3. Which of the following NTFS features is incompatible with EFS encryption?
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. It’s important to protecting our assets that might be on portable devices to prevent the theft, use two factor authentications, and encrypt your data. Protecting your privacy by using strong passwords, adjusting the privacy settings on your computer, and surf the web anonymously. Other ways to protecting your privacy may include e-mail anonymously by reporting spam to your email provider and knowing what information on your emal is creditable, and by erasing your Google search history to prevent important history from being discovered. | 2.
A software RAID can also be affected if the host computer is heavily loaded. Heavy processing can cause some pieces of data to be delayed by a small amount of time. These delays can add up, and negate the benefits of the RAID array to some degree. NOTE: A good website to use for RAID illustration is – Http://www.lascon.co.uk/d008005.html References Knowledgebase. (n.d.).
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.
McBride should make sure that their website is properly optimized for search engine so that consumers can easily search and find their website. McBride should also make sure they do not participate in unethical techniques like email spamming, website phishing or keyword stuffing (the practice of loading a webpage with keywords or numbers in an attempt to manipulate search engine results (Keyword Stuffing, n.d.)). These types of tactics can have a negative impact on the reputation of
