What is Information Security?
Information security means that the confidentiality, integrity and availability of information assets is maintained.
Confidentiality: This means that information is only used by people who are authorized to access it.
Integrity: It ensures that information remains intact and unaltered. Any changes to the information through malicious action, natural disaster, or even a simple innocent mistake are tracked.
Availability: This means that the information is accessible when authorized users need it.
Information Security Threats:
Most common types of information security threats are:
Theft of confidential information by hacking
System sabotage by hackers
Phishing and other social engineering attacks
Virus, spyware and malware
Social Media-the fraud threat
Theft of Confidential Information:
One of the major threat to information security is the theft of confidential data by hacking. This includes theft of employee information or theft of trade secrets and other intellectual property (IP).
Theft of Employee Information
Employee information includes credit card information, corporate credit card information, social security number , address, etc. It also includes theft of healthcare records as they contain personal information such date of birth, address, and name of relatives.
Theft of Trade Secrets and other Intellectual Property (IP)
Technology from various verticals including IT, aerospace, and telecommunications are constantly stolen by outsiders or insiders (industrial espionage). China is a growing offender as it continues to advance in technology relying on theft of international trade secrets and IP.
Piracy/copyright infringement.
Corporate business strategies including marketing strategies, product introduction strategies.
System Sabotage:
What is system sabotage?
Planting malware on networks of target organization and generating an enormous amount of transaction activity resulting in malfunction or crash of the system.
Who would perpetrate it?
System sabotage is usually committed by disgruntled ex-employees and by remote cyber-attackers for no particular reason.
The most sensational case of system sabotage: One of the recent examples is the sabotage of Sony PlayStation.
Phishing:
To obtain confidential data about individuals-customers, clients, employees or vendors that can be used to commit various types of identity fraud such as:
Opening bank accounts in victim’s name
Applying for loans in victim’s name
Applying for credit cards in victim’s name
Obtaining medical services in victims name (e-death)
Other kind of more sophisticated social engineering attacks include spear-phishing.
Spear-phishing targets specific individuals such as AP manger, controller, senior accountant to gain access to corporate bank accounts and transfer funds abroad.
Other threats include:
Smishing: Phishing via SMS (texting)
Vishing: Phishing via voice (phone)
Mobile hackin
Web applications are arguably the most important back-end component of any online business. They are used to power many of the features most of us take for granted on a website

Devoid Web Application From SQL Injection AttackIJRESJOURNAL
ABSTRACT: The entire field of web based application is controlled by the internet. In every region, World Wide Web is hugely necessary. So, network assurance is badly assuring job for us. Several kind of attacker or application programmer is attempting to split the immunity of information and destroy the instruction composed in the database. The SQL Injection Attack is very large safety measure risk in that present day. The indicated attacks allow to attacker’ s unlimited access from the database or still authority of database those determine web based application. That manages conscious and secret records and put the injurious SQL query put to modify the expected function. Many database reviewer and theorist give distinct concept to avoid regarding SQL Injection Attack. But no one of the concept is completely adaptable to. This research introduces a latest framework to protecting web based application from the SQL Injection Attack. Introduced framework i.e. present in this research is based on two techniques known as SQM (SQL Query Monitor) and Sanitization Application. That is the two ways filter program which analyses the user query and generate a separate key for user before it is sent to the application server. Several aspects of SQL Injection Attack are also discussed in that research.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

I. Introduction
In recent years, inclusion of internet in almost every type of business transaction resulted into rapid
advancement in the dependency towards information technologies. The information technology used by the
general masses for the reasons such as commercial transactions, educational transactions and other countless
activities related to finance. The use of the internet to accomplish important odd jobs, such as transactions of
balance from bank accounts, always remains under security threat. Present web sites legging behind to keep
their users data confidential till years of doing secure business online and due to which these industries have
become experts in intelligence information security. The data management systems besides these secure
websites collect non-potent data along with secure information, in this way, the potent information owner‟s
quick access while jamming break-in attempts from intruders. The most common break-in strategy is to try to
access sensitive information from a data storage by generating a query that cause the data parser to malfunction
and thereby applying this query to the desired database. This above said approach to gaining un ethical access to
private information is called SQL injection.
Since databases are anonymous and can be accessed from the internet, combating with SQL injection has
emerges as more important than ever. The current database management system comprises with little
vulnerability, the Computer Security Institutions have discovered that every year about half of the databases
experience at least one security breaching attempt and the revenue losses associated with such attempts has been
estimated more than $4,000,000.00.
II. Literature Review
Moreover, recent researches published by the “Imperva Application Defense Center” propounded that minimum
92% of website data and applications are prone to malicious attacks (M. Muthuprasanna & Kothari, 2007). To
enhance understanding of SQL injection, it is better to have good understanding of the kinds of communications
that take place during a typical session between a user and a web based application. The figure below describes
the typical communication exchange in between all the composites in a typical web application systems.
ABSTRACT
Structured Query Language (SQL) injection, in present scenario, emerges as one of the most
challenging fact to effect on the online business, as it can expose all of the business transaction
related sensitive information which is stored in online database, inclusive of most highly secured
sensitive information such as credit card passwords , usernames, login ids, credentials, phone, email
id etc. Structured Query Language injection remain a responsibility that when intruder gets the
ability with SQL related queries which is passed to a back-end database. The query which is passed
by the intruder to the data, can allow the query to data which is an assisting element with database
and required operating system. Every SQL Query that allows the inputs from the attacker sides can
defect our real web application. Intruder which attempts to insert defective SQL query into an entry
field to extract the query so that they can dump the database or alter the database which is known as
“code injection technique” and this type of attacker is also called attack vector for websites and
usually used by any type of SQL database. Through this research paper, our endeavour is to
understand the methodology of SQL injection and also to propose solution to prevent SQL Injection
in one of the most vulnerable field of E commerce.
Keywords: Business, database, effect, Intruder, injection, query, solution, etc
2. Prevention of SQL injection…
www.ijceronline.com Open Access Journal Page 2
After reviewing numerous electronic journals, articles from IEEE/FCI journals and gathered information
provides sufficient knowledge about SQL injection, it‟s attacking methodology and its prevention. The
successive review of distinctive papers is presented herewith.
Gregory T. Buehrer, Bruce W. Weide, and Paolo A. G. Sivilotti, in the research paper “Using Parse
Tree Validation to Prevent SQL Injection Attacks” publishes there commendable work in 2005. The techniques
for sql injection discovery seems impressive as this paper also covered the SQL parse tree validation very
specifically which is mentionable.
Zhendong Su and Gary Wassermann, in 2006 published their research in SQL injection entitled “The
Essence of Command Injection Attacks in Web Applications” and covered the specific methods to check and
sanitize input query using SQLCHECK, it use the augmented questions and SQLCHECK grammar to validate
query.
Stephen Thomas and Laurie Williams, worked so long in the field of SQL injection and in 2007, in their
research paper, entitled “Automated Protection of PHP Applications against SQL-injection Attacks” they
covered an authentic scheme to protect application automatically from SQL injection intrusion. This authentic
approach combines static, dynamic analysis and intelligent code re-engineering to secure existing properties.
Ke Wei, M. Muthuprasanna & Suraj Kothari in 2007, published their work entitled “Preventing SQL Injection
Attacks in Stored Procedures” and through this they provides a novel approach to shield the stored procedures
from attack and detect SQL injection from websites. Their method includes runtime check with subsequent
application code analysis to eliminate vulnerability to attack. The key method behind this vulnerability attack is
that it modifies the composition of the original SQL statement and identifies the SQL injection attack. The
process is divided in two instalments, one is off-line and another one is run-time in real time basis. In the off-
line phase, previously stored procedures uses a parser to pre-process and detect SQL statements in the working
call for run-time analysis but in the run-time phase, the technique monitors all run-time generated SQL queries
related with the user input and checks these with the original structure of the SQL statement after getting input
from the user.
III. Principle
Web based applications have SQL injection susceptibilities as they do not disinfect the inputs they use to
construct fabricated desired output. The gathered code is remains from an online storage system. The web-site
provides user‟s input field to allow the user to keep their secret information, such as credit card/debit card
password, etc. which user can use for future purchases conveniently. Replace method used to escape the quotes
so that any single quote characters in the input are considered to be literal and not a string delimiters. Replace
method is intended to block attacks by preventing an attacker from ending the string and adding SQL injection
code. Although, card-type is a numbering column, if an attacker passes 2 OR 1-1 as the card type, all account
numbers in the database will be returned and displayed on the screen.
3. Prevention of SQL injection…

Fig: System composition of SQLCHECK
IV. Methodology:
SQL injection is widely used hacking technique, in which the intruder adds SQL statements using a web
application as input fields to access to the secret users resources and due to lack of input Validation in web
applications causes intruders to be successful in hacking.
With above said technique, we can assume that a Web application receives a “http//” request from a user client
as Input and generates a SQL statement as output for the back-End database server. For example an
administrator will be authenticated after providing input as -
Typing: employee id - 0112
and password =admin, configure
That describes a login by a suspecious user exploiting sql Injection vulnerability .
Usually, it is structured in three phases,
(1) An Intruder sends the malicious “http//” request to the Web application,
(2). Generates the sql statement,
(3). Dedicatedly Deposited the sql statement to the back end database.
Fig: Example methodology of SQL Injection.
4. Prevention of SQL injection…
www.ijceronline.com Open Access Journal Page 4
As per the principle, they track through the program and the substrings received from user input and filters that
substrings immediately. The endeavour behind these program remains blocking the malicious queries in which
the incoming substrings changes the syntactic morphology of the rest of the queries. They use the metadata to
analyse user‟s input which displayed as ( „_‟ ) and ( „_,‟ ) to mark the ending and beginning of the each user
incoming string. This said metadata passes the incoming string through an assignments, and concatenations, so
that when a query is ready to be sent to the database, it has a matching pairs of markers that identify the
substring from the input. These annotated queries called an augmented query. To construct a parser for the
augmented grammar and attempt to parse each augmented query Steve use a parse generator. Query meets the
syntactic constraints and considered legitimate if it passes successfully. Else, it fails the syntactic constraints and
interprets it as an SQL injection attack.
As per the system architecture of the checking system shows in Figure above, the Grammar of the outgoing
data language is used to build SQLCHECK and a policy mentioned permitted syntactic forms, it resides on the
web server and taps generated queries. In spite of the input‟s source, each input which is to be passed into some
query, gets augmented with the meta-characters („_‟) and („_,‟).
Finally application creates augmented queries, which SQLCHEKCK attempts to parse, and if a query parses
successfully, SQLCHECK sends it the meta-data to the database, else the query get rejected.
.
V. Observation
Moreover, developers deploy defensive coding but they are not enough to stop SQL injections to web
applications, that is why researchers have proposed some of tools to assist developers to prevent there. It is
mentionable that there are more approaches which have not implemented a tool yet. In this paper, we emphasize
more on tools and less on techniques. Huang and colleagues propose WAVES, a black box technique for testing
web applications for SQL injection vulnerabilities. The tool identify all points a web application that can be
used to inject SQLIAs. It builds attacks that target these points and monitors the application how response to the

VI. Conclusion
SQL injection intrusions remain a serious problem for developers as they can be used to break into supposedly
secure systems and copy, alter, or destroy data. It becomes very easy to leave yourself vulnerable to these
attacks, regarding of which version of .NET. In fact, you don't even need to be using .NET to be susceptible to
SQL injection attacks. Any further implecations that queries a database using user- entered data set, including
Windows Forms applications is a potential target of an injection attack.
Protecting user against SQL injection attacks is less difficult. Uses which are immune to SQL injection attacks
validate and sanitize all user input, never use dynamic SQL injection, perform using an account with few
privileges, hash or encrypt their secrets, and present error messages that reveal little if no useful information to
the hacker. By following a multi-layered approach to prevention you can be assured that if one defence is
circumvented, you will still be protected. For information on testing your application for injection
vulnerabilities, see the sidebar "Injection Testing".
