Right click on the public key file that your partner sent you b. Click on More GpgEx Options and Import keys. 3. Encrypt a file using your partner’s public key and ask your partner to encrypt a file using your public key. Exchange the encrypted files. a.
It uses a 128 bit shared secret key to decrypt and encrypt data being sent through the VPN. AES is a form of symmetric encryption meaning that the data is encrypted and decrypted by using the same Pre Shared Key.
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.
The information must be kept top secret at any cost. At ABC Institute, the researchers are unsure about the type of key (asymmetric or symmetric) to use. Please formulate a possible solution, and describe the advantages and disadvantages of any solution employed. SEC 280 Week 4 Computer security is not an issue for organizations alone. Anyone whose personal computer is connected to a network or the Internet faces a potential risk of attack.
2.1 Describe the features of manual and electronic information storage systems that help ensure security. Ensure sensitive and private information is kept in secure/locked drawers or cabinets when not in use. Electronic databases should be protected by adequate spy and virus software. Electronic files should be password protected. Information pertaining to individuals should only be shared on a ‘need to know’ basis.
It also must be approved at the end of the activity to verify if it is done correctly. Security controls are an important part of securing the systems. Without this, access to vital systems can be easy to obtain. Layered security would be sufficient to offer and is a great strength along with consistent monitoring of the system. The weaknesses would rely on the type of encryption used, if any, and any type of weak token encryption.

Cryptography is a way for us to encrypt data from hard drives, emails, when data is traversing networks and data between web browsers and web servers. Utilizing symmetric key encryption will allow for secure data to be transmitted with an exception, the data must traverse a secured network channel. This can be accomplished with the utilization of a VPN or virtual private network. I would recommend using a SSL VPN system or Secure Sockets Layer. These provide a high level of security and are known as a clientless method.
A good way to do this is to encrypt all data store in the databases, as well as setup a firewall and Layer 4 router. Employees can logon to the system from abroad using a smart-card over ssl connection, which provides 3 layers of security in their communications: Encryption from the ssl connection, an employee’s private smart card certificate, and the employee’s pin number to utilize the smart card. Authentication can be handled by the layer 4 router, while the firewall can fend off would be attackers. No communication from the company to its assets should be unencrypted, and should use at the least a 2048bit SSL
