Text-Steganography Algorithm

Finally, section 7 introduces the conclusions. 2. Basic Structure of Steganography Steganography is not only the art of hiding data but also hiding the fact of transmission of secret data. It hides the secret data in another file in such a way that only the recipient knows the existence of message. In ancient time, the data was protected by hiding it on the back of wax, writing tables, and stomach of rabbits or on the scalp of the slaves.

It is nothing but to communicate in such a way that not only the contents are hidden but also the existence of message is kept secret which makes it different from cryptography which concerns only with keeping the contents secret. Steganography and cryptography they both have the same purpose that is, to provide security to our data. But, they have a different approach. Steganography deals with making the data unseen and cryptography deals with making the data unreadable. So finally,we can say that the cryptography deals with the privacy of data and steganography deals with the secrecy of data.

Cryptography is one of widely used technique of secret writing which is the term used for data and information security and protects that information from various attacks. Cryptography is the process of converting a known text or plaintext into a human unreadable format called cipher text by encoding the original message using some encoding technique. Security is concerned with the protection of the network and data transmission over the network. Data Security is the most essential aspect of secure data transmission over the network. But to achieve complete data security is a challenging issue of data communication.

Setting file permissions is a form of DAC because it is the owner’s discretion. Configuring as many security layers as the user can will ensure the server will stay secure. Not all OS are 100% secure, but they can be configured to make it very hard for a hacker to

P8.4. a. Preventive controls such as authentication so anyone trying accessing the system has to provide credentials and verify their identity, encryption so sensitive information cannot be accessed, and have a strong internal environment that educates employees on security measures. Detective controls such as log analysis could be used to show determine if someone is trying to log on to a system and is unsuccessful. Corrective controls such as having an effective CIRT that can access the laptop and block or delete important information so the theft cannot access the laptop.

If you think your phone is secure, it is still vulnerable to pilfer your data. Now a day’s hacker does not need physical access to the phone. They can infect your device with the virus or steal your personal information using malicious applications remotely. You can keep away your phone from hackers by taking the 10-smartphone security steps. Step 01:

Cryptography is a technique or method to secure personal data from unauthorized user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand.

According to beckershospitalreview.com “Self-encrypting hard drives provide Source: iamwire.com stronger protection.” Encryption “uses a complex algorithm called a cipher in order to turn normalized data (plaintext) into a series of seemingly random characters (ciphertext) that is unreadable by those without a special key in which to decrypt it (makeuseof.com).” This is a very valuable asset to hospitals because if they ever got hit with a cyber attack the hackers wouldn’t be able to see what the data

Biometric Access Control (ABAC) system is expected to certify and authenticate membership status of the user by employing biometric signals without prior knowledge of their true identity. This might help curb possibilities of security access breaches by hackers and imposters which can sabotage the integral purity of the information within the University of Botswana database servers. Hypothetically speaking a solution could be achieved through the use of biometrical access control systems as this paper mainly focuses on access control. KEYWORDS;  Biometric  Prurity  Hackers 

Abstract Now a days, security of the confidential information of the organization or an individual become a serious issue. Because of vulnerability of system allow to unauthorized person to access the confidential information or data . Because of unauthorized access the confidentiality of information get break. So, biometrics is a good technique to maintain the security of the confidential data.

At least one character should be a Digit. 4. Symbols and Non alphabetic characters. Reversible Encryption:

If the request is valid then it is further checked for other attacks, otherwise it is blocked and stored in the log with the attack type that is found in that request. In HTTP request smuggling attack, a malicious request contains multiple start lines that are not allowed in one HTTP request (violation of RFC 2616). When the hacker tries to assign multiple start lines to one request, it will be detected by the system analyzer and reported as an HTTP request smuggling attack. A buffer overflow is the computing equivalent of trying to pour two liters of water into a one-liter pitcher, some water is going to spill out and make a mess.

Misuse detection is used to identify previously known attacks for which they require before hand knowledge of attack signature. the disadvantage of this method is that prior knowledge of the attack is required and hence new attacks cannot be identified until new attacks signature have been developed for them. In anomaly detection system monitors activity to detect any significant deviation from normal user behavior compared to known user standard behavior, this type of intrusion detection can effectively protect against both well known and new attacks since no prior knowledge about intrusion is required. One of the most significant aspects of Intrusion Detection System is the use of Artificial Intelligence techniques[39] to train the IDS about possible threats and gather information about the various traffic patterns to infer rules based on these patterns to distinguish between to differentiate between normal and intrusive

The MSVCP110.dll file is corrupt. Problem of Malware. Issues with hardware. Once we are familiar with the causes, we can now move towards the solutions.

It is risky. Hackers could steal such passwords without your knowledge. You should rather install a reputable password manager to remember your passwords. 4. Don’t use the same password for all your online accounts.
