Six Powerful Attacks In Cyber world .

 



Six Big Attacks


1. DDOS Attack

 

* A Distributed Denial of Service  Attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources.


2. Phishing.


* Phishing attack attempt to gain sensitive, confidential information such as usernames, passwords, credit card information, network credentials, and more .


3. Backdoor.


* A Backdoor is a means to access a computer system or encrypted data that bypasses the system's customary security mechanisms. A developer may create a backdoor so that an application or operating system can be accessed for troubleshooting or other purposes. 


4. Man in the middle attack.


* A Man In The Middle attack (MITM) is an attack against a cryptographic protocol. As the name implies, in this attack the attacker sits in the middle and negotiates different cryptographic parameters with the client and the server .


5. SQL injection.


* A SQL injection attack consists of insertion or “injection” of a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system and in some cases issue commands to the operating system. SQL injection attacks are a type of injection attack, in which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands.


6. Ransomeware. 


* Ransomware is malicious software that infects your  computer and displays messages demanding a fee to be paid in order for your system to work again. This class of malware is a criminal moneymaking scheme that can be installed through deceptive links in an email message, instant message or website.

Polymerase Chain Reaction (PCR) and its Applications

Image
Polymerase Chain Reaction (PCR) PCR is an enzymatic process in which a specific region of DNA is replicated over and over again to yield many copies of a particular sequence. This method combines the principles of complementary nucleic acid hybridization with those of nucleic acid replication applied repeatedly through numerous cycles. The most widely used target nucleic acid amplification method is the polymerase chain reaction (PCR). This method is able to amplify a single copy of a nucleic acid target, often undetectable by standard hybridization methods, and multiply to 10 7  or more copies in a relatively short period. This thus provides ample target that can be readily detected by numerous methods. APPLICATIONS OF PCR PCR can amplify a single DNA molecule from a complex mixture, largely avoiding the need to use DNA cloning to prepare that molecule. Variants of the technique can similarly amplify a specific single RNA molecule from a complex mixture. DNA sequencing has been greatl

REAL TIME PCR and its Application notes

Image
REAL TIME PCR   Real-time polymerase chain reaction ( qPCR ) is commonly used to measure gene expression . It is more sensitive than micro arrays in detecting small changes in expression but requires more input RNA and is less adaptable to high-throughput studies.  It is best suited for studies of small subsets of genes.  Its one major shortcoming is that the sequence of the specific target gene of interest must be known (so you can design the PCR primers),  hence real-time PCR can only be used for studying  known genes .   It is also known as a  quantitative polymerase chain reaction (qPCR) , which is a laboratory technique of molecular biology based on the polymerase chain reaction . PRINCIPLE OF REAL TIME PCR(qPCR). This same principle of amplification of PCR is employed in real-time PCR. But instead of looking at bands on a gel at the end of the reaction, the process is monitored in “real-time”. The reaction is placed into a real-time PCR machine that watches the reaction occur wi
