Secure web programming plus end users' awareness are the last line of defense against attacks targeted at the corporate systems, particularly web applications, in the era of world-wide web.
Most web application attacks occur through Cross Site Scripting (XSS), and SQL Injection. On the other hand, most web application vulnerabilities arise from weak coding with failure to properly validate users' input, and failure to properly sanitize output while displaying the data to the visitors.
The literature also confirms the following web application weaknesses in 2010: 26% improper output handling, 22% improper input handling, and 15% insufficient authentication, and others.
Abdul Rahman Sherzad, lecturer at Computer Science Faculty of Herat University, and Ph.D. student at Technical University of Berlin gave a presentation at 12th IT conference on Higher Education for Afghanistan in MoHE, and then conducted a seminar at Hariwa Institute of Higher Education in Herat, Afghanistan introducing web application security threats by demonstrating the security problems that exist in corporate systems with a strong emphasis on secure development. Major security vulnerabilities, secure design and coding best practices when designing and developing web-based applications were covered.
The main objective of the presentation was raising awareness about the problems that might occur in web-application systems, as well as secure coding practices and principles. The presentation's aims were to build security awareness for web applications, to discuss the threat landscape and the controls users should use during the software development lifecycle, to introduce attack methods, to discuss approaches for discovering security vulnerabilities, and finally to discuss the basics of secure web development techniques and principles.

Microsoft powerpoint presentation for BTech academic seminar.This seminar discuses about penetration testing, penetration testing tools, web application vulnerabilities, impact of vulnerabilities and security recommendations.
Introduction of Ethical Hacking, Life cycle of Hacking, Introduction of Penetration testing, Steps in Penetration Testing, Foot printing Module, Scanning Module, Live Demos on Finding Vulnerabilities a) Bypass Authentication b) Sql Injection c) Cross site Scripting d) File upload Vulnerability (Web Server Hacking) Countermeasures of Securing Web applications
This presentation will provide an overview of what a penetration test is, why companies pay for them, and what role they play in most IT security programs. It will also include a brief overview of the common skill sets and tools used by today’s security professionals. Finally, it will offer some basic advice for getting started in penetration testing. This should be interesting to aspiring pentesters trying to gain a better understanding of how penetration testing fits into the larger IT security world.

Application Security - Your Success Depends on itWSO2
Traditional information security mainly revolves around network and operating system (OS) level protection. Regardless of the level of security guarding those aspects, the system can be penetrated and the entire deployment can be brought down if your application's security isn't taken into serious consideration. Information security should ideally start at the application level, before network and OS level security is ensured. To achieve this, security needs to be integrated into the application at the software development phase.
In this session, Dulanja will discuss the following:
The importance of application security - why network and OS security is insufficient.
Challenges in securing your application.
Making security part of the development lifecycle.
OWASP Top 10 2021 – Overview and What's New.
OWASP Top 10 is the most successful OWASP Project
It shows ten most critical web application security flaws.
Read the presentation and you will learn each OWASP Top 10 category and recommendations on how to prevent it.
This presentation describes penetration testing with a Who, What, Where, When, and How approach. In the presentation, you may discover the common pitfalls of a bad penetration test and you could identify a better one. You should be able to recognize and differentiate both looking at the methods (attitude) and result.

What Makes Web Applications Desirable For HackersJaime Manteiga
For years’ unethical hackers have preferred Web Applications as the favorite pattern of attack. In this webinar, we will take a look inside the mind of an attacker — including uncovering their motivation and hacking techniques. Web Applications become compromised all the time; additionally, organizations seem to be repeating mistakes when it comes to application security. This webinar will serve as a baseline to establish appropriate web information security controls and mitigation strategies by thinking like an unethical hacker.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

19. Canyourbusinesssurvivewithoutdata?
XSS flaws occur whenever an application
takes user supplied data and sends it to a
web browser without first examining the
content. XSS allows attackers to execute
script in the victim’s browser which can

script in the victim’s browser which can
hijack user sessions, deface web sites,
possibly introduce worms, etc.
20. Canyourbusinesssurvivewithoutdata?
Injection flaws, particularly SQL injection,
are common in web applications. Injection
occurs when user-supplied data is sent to
an interpreter as part of a command or
query. The attacker’s hostile data tricks the

query. The attacker’s hostile data tricks the
interpreter into executing unintended
commands or changing data.
21. Canyourbusinesssurvivewithoutdata?
Code vulnerable to remote file inclusion
(RFI) allows attackers to include hostile
code and data, resulting in devastating
attacks, such as total server compromise.
Malicious file execution attacks affect PHP,
www.ebusinessmantra.com
Canyourbusinesssurvivewithoutdata?
Malicious file execution attacks affect PHP,
XML and any framework which accepts
filenames or files from users.
22. Canyourbusinesssurvivewithoutdata?
A direct object reference occurs when a
developer exposes a reference to an
internal objects, such as a file, directory,
database record, or key, as a URL or form
parameter. Attackers can manipulate those

Canyourbusinesssurvivewithoutdata?
parameter. Attackers can manipulate those
references to access other objects without
authorization.
23. Canyourbusinesssurvivewithoutdata?
A CSRF attack forces a logged-on victim’s
browser to send a pre-authenticated
request to a vulnerable web application,
which then forces the victim’s browser to
perform a hostile action to the benefit of
www.ebusinessmantra.com
Canyourbusinesssurvivewithoutdata?
perform a hostile action to the benefit of
the attacker. CSRF can be as powerful as
the web application that it attacks.
24. Canyourbusinesssurvivewithoutdata?
Applications can unintentionally leak
information about their configuration,
internal workings, or violate privacy through
a variety of application problems. Attackers
use this weakness to steal sensitive data or

Canyourbusinesssurvivewithoutdata?
use this weakness to steal sensitive data or
conduct more serious attacks.
25. Canyourbusinesssurvivewithoutdata?
Account credentials and session tokens are
often not properly protected. Attackers
compromise passwords, keys, or
authentication tokens to assume other
users’ identities.

Canyourbusinesssurvivewithoutdata?
users’ identities.
26. Canyourbusinesssurvivewithoutdata?
Web applications rarely use cryptographic
functions properly to protect data and
credentials. Attackers use weakly protected
data to conduct identity theft and other
crimes, such as credit card fraud.

Canyourbusinesssurvivewithoutdata?
crimes, such as credit card fraud.
28. Canyourbusinesssurvivewithoutdata?
Frequently, an application only protects
sensitive functionality by preventing the
display of links or URLs to unauthorized
users. Attackers can use this weakness to
access and perform unauthorized

access and perform unauthorized
operations by accessing those URLs directly.
