Read-only memory is computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read. The POST beep codes make troubleshooting a computer start-up problem easier because without the codes a user would not know what was wrong with computer. There are so many different problems that can occur when your computer breaks down. Having beep codes to help decipher the problem makes the repairs easier.
By proper end user training for anyone involved with the Corporate Techs site, proper scanning of all USB and thumb drives on a test computer being used for this particular site, can mitigate threats from bugs and viruses. Also, by changing all local computer default autorun policies, will disable usage of these USB ports and stop an occurrence from taking place. Last, it’s almost near impossible for an end user to not use a personal laptop during work hours for personal use or for work. But to mitigate further problems from happening, I will implement an encrypted file system for sensitive data. TrueCrypt is a program that I have found efficient that controls over endpoints that enter and exit the internal system.
If the anti-virus software does not contain anti-malware software, I would load the software program and check for any malware. After checking the computer for any viruses or malware, I would have the person change his password.
Spyware is almost exactly as it sounds, a spying program. This type of malware will record the users input and transmit it back to the hacker to access at his leisure. This type of spyware is called a key logger and can capture interesting information such as user names, passwords, credit card numbers and email addresses. The more advanced versions of spyware can siphon off network data that will allow the hacker access to files, encryption keys, and other sensitive information. The final malware I will cover is the zombie.
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. 2. Secure Configurations for Hardware and Software on Mobile Devices, Laptops, Workstations and Servers – establishing and ensuring that proper security configurations are always in use on your operating system will keep new devices safe from outside attacks. Updating these configurations on a regular basis will also ensure that all devices connected to the system are properly secure and not an open back door for unauthorized entry. Always conduct updates and implementation of configurations on a secure channel to avoid channel sniffing.
The current policy states that all firewalls and routers are evaluated every two years and that all local servers are backed up to storage devices that are attached to the network and are maintained at the server location. This security policy is ineffective as it is not complete. Strong security policies should state acceptable and unacceptable user behavior, restrictions to resources, and conform to the company’s business plan (Firewall Design, 2012). The policy should include the specific IP addresses users are allowed to access as well as their specific destination ports. The components that make up the security policy as well as the security policy itself should be simple enough for administrators to change and troubleshoot errors but strong enough to keep unwanted access out (Firewall Design,
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
So it allows for multiple users to access and edit the data simultaneously, and the database stores these changes until it is time for the update. Each day or at another time specified by the DBMS, the database begins updating. It starts with the first timestamp and works it's way through the list so that the updates occur in the order in which they happened so the new information is correct. 12. What is journaling?
Security Risks Stacey Matthews University of Phoenix CMGT/442 Ted Glasser January 21, 2013 Brokers providing their own laptop-All the laptops should have the same capacity and programming installed on the computer. If each laptop is different and does not contain the proper protection, then there is a big security risk. One laptop can become filled with viruses if it does not have anti-virus software put on. One laptop that is not compatible enough to do the work needed, it could fail and shut down. This risk would be considered a medium risk.
No firewall can be a disaster for Huffman Trucking because it allows hackers to get in and have access to organization’s valuable information. Firewall must be implemented at this branch also from protection from hackers. A firewall blocks unauthorized access and allow authorized users. Firewalls can be implemented in hardware or software to ensure unauthorized Internet users are blocked from accessing Huffman Trucking’s private network (Wikipedia, 2009). Ohio Office/Plant.
