Data Tamper Detection from NoSQL Database in Forensic Environment
Abstract: The growth of service sector is increasing the usage of digital applications worldwide. These digital applications are making use of database to store the sensitive and secret information. As the database has distributed over the internet, cybercrime attackers may tamper the database to attack on such sensitive and confidential information. In such scenario, maintaining the integrity of database is a big challenge. Database tampering will change the database state by any data manipulation operation like insert, update or delete. Tamper detection techniques are useful for the detection of such data tampering which play an important role in database forensic investigation process. Use of NoSQL database has been attracted by big data requirements. Previous research work has limited to tamper detection in relational database and very less work has been found in NoSQL database. So there is a need to propose a mechanism to detect the tampering of NoSQL database systems. Whereas this article proposes an idea of tamper detection in NoSQL database such as MongoDB and Cassandra, which are widely used document-oriented and column-based NoSQL database respectively. This research work has proposed tamper detection technique which works in forensic environment to give more relevant outcome on data tampering and distinguish between suspicious and genuine tampering.
Database Security Enhancement by Eliminating the Redundant and Incorrect Spelled Data Entries
Database is used for storing the data in an easy and efficient format. In recent days large size of data has been generated through number of applications and same has been stored in the database. Considering the importance of data in every sector of digitized world, it is foremost important to secure the data. Hence, database security has been given a prime importance in every organization. Redundant data entries may stop the functioning of the database.
What exactly is Security Assurance?
If you are a regular reader of Cybersecurity Magazine, you may have come across Security Assurance before. In this article, we take a look at what is behind this abstract term and why it is so important.
Security assurance is an umbrella term for several processes aimed at ensuring individual system components can adequately protect themselves from attacks. Doing so requires not just a one-time effort, but actually spans the complete system lifecycle. After all, what is considered an acceptable security posture may change over time depending on, for example, newly emerging threats or changes to how the system itself is utilized.
A Secure Trust-aware Cross-layer Routing Protocol for Vehicular Ad hoc Networks
VANETs currently represent one of the most prominent solutions that aim to reduce the number of road accident victims and congestion problems while improving the quality of driving. VANETs form a very dynamic open network in which vehicles exchange information and warnings about road situations and other traffic information through several routing protocols, without any intermediate control.
A Boosted Performances of NTRUencrypt Post-Quantum Cryptosystem
Abstract: The bottleneck of all cryptosystems is the difficulty of the computational complexity of the polynomials multiplication, vectors multiplication, etc. Thus most of them use some algorithms to reduce the complexity of the multiplication like NTT, Montgomery, CRT, and Karatsuba algorithms, etc. We contribute by creating a new release of NTRUencrypt1024 with great improvement, by using our own polynomials multiplication algorithm operate in the ring of the form Rq=Zq[X]/(XN+1), combined to Montgomery algorithm rather than using the NTT algorithm as used by the original version.
