The following step(s) should be used to secure an operating system:

  • Test the security of the base operating system.
  • Remove unnecessary services.
  • Install and patch the operating system.

Which of the following do you protect by implementing secure real time protocol?

What are the problems with virtualization?

Organizations often have to deal with virtualization problems such as VM sprawl, network congestion, server hardware failures, reduced VM performance and software licensing restrictions. But companies can mitigate these issues before they occur with lifecycle management tools and business policies.

What are the security challenges in VMs?

While scaling, software lifecycles and diversity are just some of security challenges faced by VM developers the failure to properly implement those mechanisms may lead to VM escape, host access, denial of service and more.

What impact does virtualization have on security?

Virtualization improves physical security by reducing the number of hardware in an environment. Reduced hardware in a virtualized environment implies fewer data centers. Server virtualization allows servers to return to revert to their default state in case of an intrusion.

Which of the following security protocol is used by Protected Extensible application protocol?

PEAP (Protected Extensible Authentication Protocol) is a version of EAP, the authentication protocol used in wireless networks and Point-to-Point connections. PEAP is designed to provide more secure authentication for 802.11 WLANs (wireless local area networks) that support 802.1X port access control.

What type of security protocols you would need to secure your network?

Wi-Fi security protocols use encryption technology to secure networks and protect the data of their clients. Wireless networks are often less secure than wired ones, so wireless security protocols are crucial for keeping you safe online. The most common Wi-Fi security protocols today are WEP, WPA, and WPA2

Which of the following security protocols is used by secured file transfer protocol SFTP )?

Which of the following protocols allow(s) for secure file transfer? FTPS is an extension to the Secure Shell protocol (SSH) and runs by default on port number 22.

Which of the following security protocol protects communication between client and server?

The TLS protocol allows us to establish the following security services between two entities in a network: u2013 data confidentiality, obtained by creating a secure tunnel between the client and the server, in which data are encrypted using a symmetric cryptography algorithm, such as RC4 or AES.

Which protocol is used for transferring files?

The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network.

Which of the following is the most secure protocol?

WPA2 – Wi-Fi Protected Access 2 (WPA2) is the most secure protocol listed for connecting to wireless networks.

Which of the following is a purpose of the Secure Sockets Layer SSL software?

SSL, or Secure Sockets Layer, is an encryption-based Internet security protocol. It was first developed by Netscape in 1995 for the purpose of ensuring privacy, authentication, and data integrity in Internet communications. SSL is the predecessor to the modern TLS encryption used today.

What is the function of single socket layers SSL quizlet?

What is the Secure Socket Layer (SSL)? x26quot;TLS allows client/server applications to communicate over the Internet in a way that is designed to prevent eavesdropping, tampering, and message forgery.x26quot; SSL version 1.0 and 2.0 contained many security flaws that prompted a complete redesign of the protocol.

What is the purpose of HTTPS quizlet?

HTTPS is a secure form of HTTP that uses SSL as a sublayer for security. SSL secures messages being transmitted on the Internet. It uses RSA for authentication and encryption. Web browsers use SSL (Secure Sockets Layer) to ensure safe Web transactions.

Which of the following is true of secure sockets layer SSL and Transport Layer Security TLS?

Which of the following is true of Secure Sockets Layer (SSL) and Transport Layer Security (TLS)? SSL and TLS are protocols that provide authentication and encryption to secure transactions.

What are the three common security concerns in virtual environments?

They are:

  • Data Breaches.
  • Weak Identity, Credential, and Access Management.
  • Insecure APIs.
  • System and Application Vulnerabilities.
  • Account Hijacking.
  • Malicious Insiders.
  • Advanced Persistent Threats (APTs)
  • Data Loss.

What’s the most common security risk of virtual hosts?

An attack on one guest virtual machine escaping to other virtual machine’s resident on the same physical host represents the biggest security risk in a virtualized environment, in our view.

What are some of the risks to using a virtualized environment?
