Security Implementation Mechanisms
The characteristics of an application should be considered when deciding the layer and type of security to be provided for applications. The following sections discuss the characteristics of the common mechanisms that can be used to secure Java EE applications. Each of these mechanisms can be used individually or with others to provide protection layers based on the specific needs of your implementation.
Java SE Security Implementation Mechanisms
Java SE provides support for a variety of security features and mechanisms, including:
Java Authentication and Authorization Service (JAAS): JAAS is a set of APIs that enable services to authenticate and enforce access controls upon users. JAAS provides a pluggable and extensible framework for programmatic user authentication and authorization. JAAS is a core Java SE API and is an underlying technology for Java EE security mechanisms.
Java Generic Security Services (Java GSS-API): Java GSS-API is a token-based API used to securely exchange messages between communicating applications. The GSS-API offers application programmers uniform access to security services atop a variety of underlying security mechanisms, including Kerberos.
Java Cryptography Extension (JCE): JCE provides a framework and implementations for encryption, key generation and key agreement, and Message Authentication Code (MAC) algorithms. Support for encryption includes symmetric, asymmetric, block, and stream ciphers. Block ciphers operate on groups of bytes while stream ciphers operate on one byte at a time. The software also supports secure streams and sealed objects.
Java Secure Sockets Extension (JSSE): JSSE provides a framework and an implementation for a Java version of the SSL and TLS protocols and includes functionality for data encryption, server authentication, message integrity, and optional client authentication to enable secure Internet communications.
Simple Authentication and Security Layer (SASL): SASL is an Internet standard (RFC 2222) that specifies a protocol for authentication and optional establishment of a security layer between client and server applications. SASL defines how authentication data is to be exchanged but does not itself specify the contents of that data. It is a framework into which specific authentication mechanisms that specify the contents and semantics of the authentication data can fit.
Tales of modern day data breaches - a web security guide for developersJaap Karan Singh
Despite increasing application security budgets, testing platforms and tools, the same security errors are routinely found in applications day after day, year after year. According to a 2018 industry report, 21% of data breaches were caused by a software vulnerability.
This presentation will walk through recent data breaches such as the Facebook Access Token security breach that affected 90 million users. We will do a technical deep dive into the coding flaws that led to these breaches and what lessons they can teach developers.
Confident Technologies provide out-of-band, multifactor authentication using a highly secure and easy-to-use, image-based approach. Learn more at www.confidenttechnologies.com
Contextual Authentication, also known as Risk-based Authentication, is matching the level of authentication to the expected impact of the surrounding events. Simply put, contextual authentication dynamically establishes the level of credibility of each user in real-time and uses this information to change the level of authentication required to access an application.
Tutorial: http://pg.portalguard.com/contextual_authentication_tutorial
This presentation talks about various access management topics in IAM domain like authentication, authorization, MFA, Password less authentication, certificate based authentication SSO protocols like SAML, OIDC.

Introductory talk to PicketLink from Federation through to Identity Management.
What is PicketLink?
PicketLink is an umbrella project for security and identity management for Java Applications. PicketLink is an important project under the security offerings from JBoss.
A Picket Fence is a secure system of pickets joined together via some type of links. Basically, the Pickets by themselves do not offer any security. But when they are brought together by linking them, they provide the necessary security.
This project is that link for other security systems or systems to bring together or join, to finally provide the necessary secure system.
For more information visit http://picketlink.org/
Defines a framework for authentication service using the X.500 directory.It is the Repository of public-key certificates,Based on use of public-key cryptography and digital signatures.
This presentation will give you short and not very technical overview about claims-based authentication.
The claims-based authentication will be the way to almost all Microsoft web-based platforms around. It is more complex than old username-password method but also more secure and general.
Design and Configuration of App Supportive Indirect Internet Access using a ...IJMER
Nowadays apps satisfy a wide array of requirements but are particularly very useful for educational institutions trying to realize their mobile learning systems or for companies wishing to bolster their businesses. A company/institute that wants to perform web filtering, caching, user monitoring etc. and allow Internet access only after authentication might use an explicit proxy. It has
been observed that most of the apps that need to connect to the Internet through an explicit proxy, do not
work whatsoever. In this paper, a solution has been proposed to get the apps working without having to
avoid the use of a proxy server. The solution is developed around transparent proxy and makes use of a captive portal for authentication. Oracle VM VirtualBox was used to develop a test bed for the experiment and pfSense was used as the firewall which has both proxy server and captive portal services integrated on a single platform. When tested, Windows 8 apps as well as Ubuntu apps worked well without sacrificing proxy server services such as web filtering. The proposed solution is widely
applicable and cost-effective as it uses open source software and essentially the same hardware as used
for explicit proxy deployments.
Authentication and Authorization ModelsCSCJournals
In computer science distributed systems could be more secured with a distributed trust model based on either PKI or Kerberos. However, it becomes difficult to establish trust relationship across heterogeneous domains due to different actual trust mechanism and security policy as well as the intrinsic flaw of each trust model. Since Internet has been used commonly in information systems technologies, many applications need some security capabilities to protect against threats to the communication of information. Two critical procedures of these capabilities are authentication and authorization. This report presents a strong authentication and authorization model using three standard frameworks. They are PKI, PMI, and Directory. The trust in this approach is enabled by the use of public key infrastructure (PKI) which is applied for client two-factor authentication and secures the infrastructure. We introduce the preventive activity-based authorization policy for dynamic user privilege controls. It helps prevent successive unauthorized requests in a formal manner. At the core, we apply the Multi-Agent System (MAS) concept to facilitate the authentication and the authorization process in order to work with multi-applications and multi-clients more dynamically and efficiently.

Empirical Study of a Key Authentication Scheme in Public Key CryptographyIJERA Editor
Public key cryptosystem plays major role in many online business applications. In public key cryptosystem, public key need not be protected for confidentiality, but the authenticity of public key is needed. Earlier, many key authentication schemes are developed based on discrete logarithms. Each scheme has its own drawbacks. We developed a secure key authentication scheme based on discrete logarithms to avoid the drawbacks of earlier schemes. In this paper, we illustrate the empirical study to show the experimental proof of our scheme.
Remote Access and Dual Authentication for Cloud StorageIJMER
Cloud computing is an emerging technology, which provides services over internet such as
software, hardware, network and storage. The key role for cloud computing is virtualization which
reduces the total cost and gives reliable, flexible and secured services. However compute service are
chosen between the providers located in multiple data centres. One of the major security concerns
related to the virtualization and the Storage where the outside attackers can use the files in the storage
and the data owners are not capable of knowing attacks. In this paper we proposed a high level
authentication for the cloud user and remote monitor controlled of your cloud storage. Here our model
provides the dual authentication for the cloud and to get the runtime record of the logs and the secured
application controls, the logs are remotely accessed and controlled by the owner of the data.

• Authorize ,Authenticate ,Provide data confidentiality
,Monitor access.
• In addition to these principles, we will also discuss the
following security concerns:
> Malicious code
> Website attacks
4. 4
Authorization
provides a visual representation of these two approaches to security: the client-server
approach, in which the aim is to secure the client, and the J2EE approach, in which the aim is
to secure the server.
5. 5
• The onset of the Internet caused network security to become a
huge concern.
• When Java first hit the market, it was known as the Internet
language.
• It marketed applet development as the product that provided a
secure environment for clients accessing unknown sources over
the Internet.
• However,restricting applet access to the client system was not a
successful solution to security.
• Instead, other means of protection were needed to enable
authorized access without limiting functionality.
• The concern is no longer focused on the applet client, but rather
a J2EE client (servlet or JSP) attempting to access an enterprise
application.
6. 6
Authentication
• After the client identifies themselves, they must provide
evidence to prove they are truly who they claim.
• Authentication is the process whereby the client supplies
credentials to prove their identity. Most often proof is provided
via a password.
• Other examples include the swipe of a card, retinal scans,
fingerprints, or digital certificates located on the user’s system.
7. 7
Data Integrity
• Access control fails if others can gain access to password or authentication information
as it is transmitted over the network.
• Encrypting information protects data and provides another level of security.
• The protocol called Secure Sockets Layer (SSL) was developed to use public key
cryptography to encrypt communication between the client and server.
• Two main security concerns are solved when using public key cryptography:
> The first is confidentiality. Because the data is encrypted, you are
guaranteed privacy.
> The second is integrity. As long as the information can be decoded
properly by the intended recipient, you can be fairly sure that the data
was not tampered with during transmission.
8. 8
Auditing
• Auditing users is a way of ensuring that users who log in
successfully access only those resources that are
appropriate to their role.
• The servlet security model is role-based .
• This means that users are assigned to roles, such as
Manager, Employee, or Guest.
• Each role is assigned certain privileges, and access is
granted to roles rather than users.
9. 9
• To determine whether to provide a client with access to a
given resource, the server:
1. Discovers which roles are available
2.Checks to see which roles are allowed
3.Checks to see whether the user is assigned to any
available roles
10. 10
• Notice that security evolves around the role rather than the
user. By using a server-specific tool, users are mapped to
particular roles.
• The granularity of permissions can be defined at a finer level.
By using the tool or the deployment descriptor, you can specify
the method permissions for each role as well.
• Access for each role can be denoted in two ways: through
• declarative security
• or
• programmatic security.
11. 11
Declarative Security
• Declarative security uses the deployment descriptor to
specify which resource a role can access.
• The advantage of this approach is that implementing
security is independent of source code: when security
changes must be made, there is no need to recompile or
make changes to the code.
12. 12
• By including the security-constraint tag in your web.xml file
located in the /WEB-INF directory, you can define each resource
and the roles that have access.
• Here is an example of how to restrict a particular directory to
users that have the role of Administrator.
14. 14
Programmatic Security
• There are three Java methods within the javax.servlet
.HttpServletRequest class that provide information about the
user making a request:
• String getRemoteUser() : returns a String of the username
used to log in to the website.
• boolean isUserInRole(String role) : indicates whether the
user accessing the servlet is assigned to the passed-in role.
• Principal getUserPrincipal() : returns a java.security
.Principal object representing the user who is logged in.
15. 15
Here is an example of how programmatic security can filter activity based on the
user:
public class AccessServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/plain");
PrintWriter out = res.getWriter();
String username = req.getRemoteUser();
if (username == null) { out.println("You are not logged in.");
} else if ("Mary".equals(username)) { out.println("Hello Mary, glad you can
join us");
} else {
out.println("Hello " + username);
}
16. 16
This example has Mary assigned to the role of GeneralUser. With this said,
the deployment descriptor would look like the following:
• <security-constraint>
> <web-resource-collection>
<web-resource-name>
AccessServlet
</web-resource-name>
• <url-pattern> /serlvet/AccessServlet </url-pattern>
> </web-resource-collection>
• <auth-constraint>
<role-name> GeneralUser </role-name>
</auth-constraint>
</security-constraint>
• As you can see, declarative and programmatic security can be used together. The downside of
defining security measures within code is that changes to security will result in the need to
recompile the code.
17. 17
Malicious Code
• In the technical world, the term malicious code is
synonymous for virus.
• Unfortunately, many people thrive on developing software
that locates system vulnerabilities and attacks.
• Sometimes the code is kind enough to simply overflow a
particular folder with messages of love, but other times
viruses have been known to wipe out entire hard drives.
• There are no flags or method calls that can protect your
system against these types of assaults.
• One solution is the use of antivirus software.
18. 18
Website Attacks
• When establishing a website, assume the site will be attacked.
Even if the information isn’t critical, hackers often use systems
for the sole purpose of hiding their trail.
• By bouncing from machine to machine, they can arrive at a
destination with a trail too difficult to trace.
• One form of protection is the utilization of a firewall.
• Another consideration to help against attacks is the installation
of intrusion detection tools.
• There are a number of tools you can use to detect attackers.
Packet sniffers, for example, enable you to view all the traffic
on your network.
• If any activity looks odd, you can use your firewall to block the
intruder.
19. 19
Authentication Types
• The web container provides four authentication techniques
to determine client validity:
1. BASIC authentication requires the client to provide a user login name and
password in order to access protected data.
2. FORM authentication adds a bit of elegance to logging in. It enables an
application to request authorization by using a customized HTML page.
3. DIGEST authentication provides a little bit more security in that it
encrypts the login name and password to prevent others from acquiring this
privileged information while it travels over the network.
4. CLIENT-CERT authentication stands for client certificate. This approach
requires the client to provide a digital certificate containing information about
the issuer, signature, serial number, key type, and more. Basically, it is a
complex object used to identify the client.
20. 20
BASIC
• The simplest form of authentication is known as HTTP Basic
authentication,or BASIC.
• As its name indicates, an application utilizing this form of
certification asks for basic information, such as the user’s
login name and password.
• The data is then transferred to the server by using BASE64
encoding for validation.
• The good news is that this process is easy to implement; the
bad news is that it doesn’t offer much security beyond
authenticating the client.
21. 21
public class PrivateServlet extends HttpServlet {
public void doGet(HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/plain");
PrintWriter out = res.getWriter();
out.println("You are accessing
private information");
}
}
22. 22
• Within the security-constraint, there are two sub-elements:
> web-resource-collection
> auth-constraint
• The web-resource-collection element defines three important
features of the protected code:
> The web-resource-name is the name used by a tool to
reference the servlet. The name must be specified even if a
tool is not used.
> The url-pattern indicates the URL pattern to the source code
requiring protection. If alias names are used to reference
servlets, those too should be included.
> The http-method indicates all HTTP methods that should
have restricted access. If no HTTP method is specified, then
all methods are protected.
Remember: the methods defined within the http-method element apply to all
servlets defined by the url-pattern element.
23. 23
The auth-constraint element defines any
number of roles that canhave access to
the protected code.
• Tomcat uses the conf/tomcat-users.xml file to characterize each
group. The file might look similar to the following:
<tomcat-users>
<user name="Mandy" password="secret" roles="Broker" />
<user name="Tim21" password="secret“ roles="Administrator" />
<user name="Bob14" password="secret" roles="Broker, Employee" />
</tomcat-users>
26. 26
FORM
• The benefit to the Form approach is aesthetic. Essentially
you can guarantee that all users, regardless of which browser
they use.
• Several requirements are necessary :
a. The form method must be POST.
b. The action or URL must be defined as j_security_check.
c. The name attribute for the username must be j_username.
d. The name attribute for the password must be j_password.
28. 28
Custom authentication form
Once again, we will keep it very simple and
define the following Error.html page:
<HTML>
<BODY>
You failed to log in successfully.
Hit the “Back” button to try again.
</BODY>
</HTML>
30. 30
DIGEST
As we have said, one of the greatest security limitations of BASIC authentication is that
information is transferred over the network in simple BASE64-encoded text.
Someone snooping the line can easily capture a client’s username and password to gain access
to the site. DIGEST adds an extra layer of security when authenticating the user.
Instead of transferring the password,the server creates a nonce, a random value that is unique.
An example of a nonce could be the client’s IP address followed by a time stamp and some
random data. It might look something like this: 127.0.0.1: 86433665446: dujehIIJRTGDKdkfj
• The client uses a secure encryption algorithm to create, or hash, a digest.
• A digest is a one-directional, encrypted value that represents data. In this case, the digest
consists of the nonce, username, and password.
32. 32
CLIENT-CERT
• HTTPS Client authentication, or CLIENT-CERT, is the strongest
form of authentication. HTTPS is HTTP over Secure Socket
Layer (SSL).
• Instead of simply providing a username and password, the client
must provide that information in addition to a personal certificate
for authorization to access the server.
34. 34
Scenarios that were previously threatening pose no or little threat when
using certificates. Here are some potential scenarios:
• If the object is retrieved during its commute to its
destination by an unauthorized receiver, that person will
be unable to extract its information because they lack the
key.
• Because the certificate also has a time stamp associated
with it, a retrieved certificate is invalidated after a period
of lapsed time; thus it cannot be forged during future login
attempts.
• Obtaining a stolen public key serves no purpose because
although it allows you to verify the person sending the
certificate, it does not grant you access to the system they
are attempting to access.
35. 35
• A common problem is known as man-in-the-middle attacks.
Someone places themselves between the client and server and
manages to intercept the authentication and pose as a valid
user.
• One solution to protecting a public key during its transfer is to
encrypt communication or use direct connections the other is to
use digital certificates.
• Digital certificates attach identity to a public key. They act like a
driver’s license or passport in that they prove you are who you
claim to be.
• A certificate contains your public key and some additional
information signed by a third party’s private key. Companies
such as Versign and Thawte, known as a certificate authority
(CA), sell certificates to individuals to enable them to sign their
public key.
