When encrypting data with a block cipher, each repetition is called software that hides on a computer and provides a back door for an attacker. To launch a distributed denial of service DDOS attack, an attacker often uses The well known port number 8. The element that automatically assigns IP addresses to LAN hosts is Dynamic Host Configuration Protocol DHCPA tool that captures packets on a network and helps you analyze that packets is An attack in which one or more hosts conspire to inundate a victim with ping requests is called a An attack that forges the senders IP address is called On the Internet, the entity that looks up a domain name and retrieves information about it is the In the Website address www. Issuing the nslookup command along with a domain name displays the corresponding IP address. Confidential company information that would give competitors a commercial advantage if leaked is called Rules that restrict certain types of information to specific groups within a company are categorized as Two person or multiperson control in important transactions helps to reduce the risk of switching provides resource efficiency and flexible routing, and permits parallel transmission. When using private addresses, there must be a gateway between the private network and the rest of the internet which performs. The encryption algorithm invented by Ron Rivest is a stream cipher, but it has weaknesses when compared to other algorithms that were created with a more open design such as AES. DES and AES are both known as ciphers in terms of the way the process of encryption is applied with these approaches. Like viruses, copy themselves to other places and spread from there to infect host computers. Often these serve no particular purpose. BCP, otherwise known as is an important aspect of managerial planning for information security in enterprises. Prince Persia Retro Pc Game. A BIA, or is a report that assesses the enterprises ability to recover from a major disaster. A standby is a computing environment that we leave idle until it might be needed in case of a disaster, and then the enterprise will install backups and populate the site. A standby is used in an enterprise needs to keep operations going at all times, and it is able to take over the work in case of disaster without any delay in operation. Windows based command used in the command shell to give information about host addresses IP and MAC addresses. Hiding an object, such as a diary, to prevent others from finding it is an example of Security through Obscurity. An algorithm is a type of An encryption algorithm that uses the same key for both encryption and decryption is The type of cipher that rearranges the text of a message is called To use symmetric cryptography, the sender and receiver must share Gilbert Vernams bit combination operation for encrypting digital teletype transfer is now referred to as Decryption is the process of reversing encryption. The two primary types of symmetric algorithms are public and cipher. The Vigenre cipher uses a series of shifts to encrypt every letter in a message. The Advanced Encryption Standard AES is stronger than the Data Encryption Standard DES. The following are common ways to handle new encryption keys except transfer them via instant messenger. A file encryption program truncates a passphrase that is too long. An Advanced Encryption Standard AES key may not be When encrypting a file, a fully punctuated passphrase should have a minimum of characters. Encrypting an encryption key using a passphrase is called Using the Diffie Hellman algorithm both participants in the exchange must have a publicprivate key pair. In a Diffie Hellman calculation using P gs mod N, s is Digital signatures are often used to provide A public key certificate generally does NOT contain After changing an encryption key, all backup copies of the protected file are also protected by the new key. The shorter the encryption key, the more difficult it is to crack. In cryptography, an internal key exists inside the encryption process and disappears when the process is not running. Elliptic curve cryptography uses the equation C Me mod N for encryption. When you visit a website with an https prefix in the address, the site is secure. An attacker can modify a file without changing the files hash value. A digital signature uses symmetric keys to sign or verify digital data. A certificate authority is a trusted third party that issues certificates on behalf of some organization. There is a single, global public key infrastructure PKI. CIA properties do NOT include 1. Confidentiality. 2. Integrity. 3. Availability. An attempt by a threat agent to exploit assets without permission is referred to as A person skilled in attacking computer systems, who uses those skills as a security expert to help protect systems, is a A security analyst is performing a security assessment. The analyst should NOT take actions to mitigate a serious risk. When disclosing a security vulnerability in a system or software, the manufacturer should avoid including enough detail to allow an attacker to exploit the vulnerability. The term security theater refers to security measures intended to make potential victims feel safe and secure without regard to their effectiveness. Authentication is a security service that ensures information is reliably available. For data to be cryptographically random, it cannot be produced by a procedure. A vulnerability is a security measure intended to protect an asset. The primary element on a computer motherboard that runs programs and makes the computer work is the central processing unit CPUIn a password system, the total number of possible passwords is called the The fundamental job of every operating system is to run programs, and this relies on 1. RAM management. 3. IO management. One of the vulnerabilities the Morris worm used was a networking service called finger. The purpose of the finger service is to report the status of individual computer users. An attack in which someone tries to trick a system administrator into divulging a password is called The process of loading and running a program from a mass storage device like a hard drive or CD ROM is called A type of security control that takes measures to help restore a system is referred to as A type of security control in which you unplug a computer from the Internet to protect it from malware is An attack that blocks access to a system by other users is called A computers Basic Input Output BIOS is a computer program stored in read only memory ROM. A stack provides a simple, structured way to give temporary storage to a procedure, including a place to save the return address. Part of the reason why the Morris worm was successful was that the finger process had Least Privilege instead of Most Privilege. Enter Pci Xl Vga Card Driver For Windows 7. In a hierarchical file system directory, the topmost directory is called the The character that separates directories in a Windows directory path is The directory access right that allows a user to search for a name in a files path but not examine the directory as a whole is called The product that creates financial fraud botnets using Zbot malware and is offered for sale on the black market is General security access controls refer to objects, rights, and The information state associated with data in motion is The main purpose of a software patch is to An example of a capability based system is 1. Kerberos. 2. public key certificates.
