Firewall is a device or set of instruments designed to permit or deny network transmissions based upon a set of rules and regulation is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass or during the sensitive data transmission. Distributed firewalls allow enforcement of security policies on a network without restricting its topology on an inside or outside point of view. Use of a policy language and centralized delegating its semantics to all members of the networks domain support application of firewall technology for organizations, which network devices communicate over insecure channels and still allow a logical separation of hosts in- and outside the trusted domain. We introduce the general concepts of such distributed firewalls, its requirements and implications and introduce its suitability to common threats on the Internet, as well as give a short discussion on contemporary implementations.

Solution
Configuration Management
The main weapon in network attack defence is tight configuration management. The following
measures should be strictly implemented as part of configuration management.
• If the machines in your network should be running up-to-date copies of the operating system
and they are immediately updated whenever a new service pack or patch is released.
• All your configuration files in your Operating Systems or Applications should have enough
security.
• All the default passwords in your Operating Systems or Applications should be changed after
the installation.
• You should implement tight security for root/Administrator passwords
Firewalls
Another weapon for defense against network attack is Firewall. Firewall is a device and/or a
sotware that stands between a local network and the Internet, and filters traffic that might be
harmful. Firewalls can be classified in to four based on whether they filter at the IP packet level,
at the TCP session level, at the application level or hybrid.
1. Packet Filtering: Packet filtering firewalls are functioning at the IP packet level. Packet
filtering firewalls filters packets based on addresses and port number. Packet filtering firewalls
can be used as a weapon in network attack defense against Denial of Service (DoS) attacks and
IP Spoofing attacks.
2. Circuit Gateways: Circuit gateways firewalls operate at the transport layer, which means that
they can reassemble, examine or block all the packets in a TCP or UDP connection. Circuit
gateway firewalls can also Virtual Private Network (VPN) over the Internet by doing encryption
from firewall to firewall.
3. Application Proxies: Application proxy-based firewalls function at the application level. At
this level, you can block or control traffic generated by applications. Application Proxies can
provide very comprehensive protection against a wide range of threats.
4. Hybrid: A hybrid firewall may consist of a pocket filtering combined with an application
proxy firewall, or a circuit gateway combined with an application proxy firewall.
Encryption
Encryption is another great weapon used in defense against network attacks. Click the following
link to get a basic idea of encryption.
Encryption can provide protection against eavesdropping and sniffer attacks. Private Key
Infrastructure (PKI) Technologies, Internet Protocol Security (IPSec), and Virtual Private
Networks (VPN) when implemented properly, can secure you network against network attacks.
Other tips for defense against network attack are
• Privilege escalation at different levels and strict password policies
• Tight physical security for all your machines, especially servers.
• Tight physical security and isolation for your back up data..

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

TOPIC:DISTRIBUTED FIREWALL,
LIMITATION OF FIREWALL.
3. SYNOPSIS
o What is firewall?
o What is distributed firewall?
o Distributed firewall concept.
o Architecture of distributed firewall.
o Components distributed firewall.
o Advantages.
o Distributed firewall implementation.
4. WHAT IS FIREWALL?
Firewall is a device
or instruments
designed to permit
or deny network
transmission based
upon a set of
rules and regulations
which are frequently
used to protect
network from
unauthorized access.
5. WHAT IS DISTRIBUTED FIREWALL?
Distributed firewall is a host resident security software
application. Which protects the network as a whole
against unwanted intrusion.
6. Distributed firewall concepts:
Distributed firewall is an
mechanisms to enforce a
network domain security
policy through the use of
policy language.
Security policy is defined
centrally.
Enforcement of policy is
done by network
endpoints where is the
hackers try to penetrate.
It filters traffic from both
the internal and internet
network.
They overcome the single
point of failure concept.
7. ARCHITECTURE OF DISTRIBUTED FIREWALLS:
FOUR CONCEPTS ARE:
The management center.
The policy actuator.
Remote endpoints connectors.
Log server.
11. POLICY LANGUAGE:
The policy language is used to create policies
for each firewall.
These policies are collection of rules, Which
guides the firewall for evaluating the network
traffic.
12. POLICY distributed scheme:
The policy distributed scheme should
guarantee the integrity of the policy during
transfer.
The policy is consulted before processing the
incoming or outcoming message.
The distributed of the policy can be different
and varies with the implementation.
13. CERTIFICATE:
There may be the chance of using IP address for the
host identification by the distributed fire walls.
But the mechanism of security is more important.
It is preferred to use certificate to identify hosts.
IPSEC provides cryptographic certificates.
policies are distributed by means of these.
14. ADVANTAGES:
o Provides security for internet and intranet.
o Multiple access points.
o Insiders are no longer trusted.
o Security policy rules are distributed and established
and needed basis.
o End to End can be easily done and filtering packet to
easy.
15. DISTRIBUTED FIREWALL IMPLEMENTATION:
Language to express policies and resolving request
(key note system).
Using key note and IPSC allows control of mixed level
policies where authentication mechanism is applied
through public key cryptography.
18. FIREWALL LIMITATIONS
A firewall is a crucial component of securing your network and is designed to
address the issues of data integrity or traffic authentication and confidentiality
of your internal network .Your network gains these benefits from a firewall by
receiving all transmitted traffic through the firewall.The importance of including
a firewall in your security strategy is apparent; however, firewall do have
following limitations:
A firewall cannot prevent users or attackers with modems from dialing in to
or out of the internal network, thus bypassing the firewall and its protection
completely.
Firewalls cannot enforce your password policy or prevent misuse of
password.
Firewalls cannot stop internal users from accessing websites with malicious
code, making users education critical.
Firewalls cannot protect you from poor decisions.
Firewalls cannot protect you when your security policy is too lax.
20. Definition:
A firewall must be configured very carefully. It effective only if it
is the only entry-exit point of an organization’s network. If,
instead, the firewall is one of the entry-exit points, a user can
bypass the firewall and exchange information with the Internet
via the other entry-exit points. This can open up the possibilities
of attacks on the internal network through those points. The
firewall cannot, obviously, be expected to take care of such
situations.
21. INSIDER’S INTRUSION
Definition:
A firewall system is
designed to the wart
outside attacks. Therefore,
if an inside user attacks the
internet network in
someway; the firewall
cannot prevent such an
attack.
