Firewalls are systems designed to control network access by enforcing an access control policy. They work by examining packets and filtering them based on rules like IP addresses, protocols, and ports. There are different types of firewalls including packet filtering, proxy, and application layer firewalls. While firewalls help protect networks from unauthorized access and provide logging, they have limitations as they only control connectivity and not other aspects of security like encryption. It is important to take additional precautions like using strong passwords, keeping software updated, and practicing safe online habits.

Cyberoam offers next-generation firewall and UTM firewall that provide stateful and deep packet inspection for network, application and user identity-based security. Cyberoam firewall appliances provide ease of management and high security with flexibility.
A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.
Firewalls have been the first line of defense in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet.
A firewall can be hardware, software, or both.

In computing, a firewall is a network security system that controls the incoming and outgoing network
traffic based on an applied rule set. A firewall establishes a barrier between a trusted, secure internal
network and another network (e.g., the Internet) that is assumed not to be secure and trusted. Firewalls
exist both as a software solution and as a hardware appliance. Many hardware-based firewalls also offer
other functionality to the internal network they protect, such as acting as a DHCP server for that
network.
A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. Packet filter is a hardware or software designed to block or allow transmission of packets based on criteria such as port, IP address, protocol.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. Firewalls – The Basics
A firewall is a system or
set of systems designed to
:
◦ Permit or deny network
◦
◦
◦
◦
transmissions
Based upon a set of rules
Used to protect networks
from unauthorized access
Permit legitimate
communications to pass.
In Effect - Enforces access
control policy
9. Problems..
Remote login - When someone is able to connect to
your computer and control it in some form. This can range from
being able to view or access your files to actually running programs
on your computer.
Application backdoors - Some programs have special features
that allow for remote access. Others contain bugs that provide
a backdoor, or hidden access, that provides some level of control of
the program.
SMTP session hijacking -. By gaining access to a list of e-mail
addresses, a person can send unsolicited junk e-mail (spam) to
thousands of users
Operating system bugs - Like applications, some operating
systems have backdoors. Others provide remote access with
insufficient security controls or have bugs that an experienced
hacker can take advantage of.
routing by default.
10. Problems…
Denial of service What happens is that the hacker sends a request to the
server to connect to it. By inundating a server with these unanswerable
session requests, a hacker causes the server to slow to a crawl or eventually
crash.
E-mail bombs - An e-mail bomb is usually a personal attack. Someone sends
you the same e-mail hundreds or thousands of times until your e-mail system
cannot accept any more messages.
Macros - To simplify complicated procedures, many applications allow you to
create a script of commands that the application can run. This script is known
as a macro. Hackers have taken advantage of this to create their own macros
that, depending on the application, can destroy your data or crash your
computer.
Viruses - Probably the most well-known threat . A virus is a small program
that can copy itself to other computers. This way it can spread quickly from
one system to the next. Viruses range from harmless messages to erasing all
of your data.
Spam - Typically harmless but always annoying, spam is the electronic
equivalent of junk mail. Especially if it contains links to Web sites.
Redirect bombs - Hackers can use ICMP to change (redirect) the path
11. Basic types of Firewalls
Hardware/ Software firewalls
Software
◦ Network Layer
◦ Application Layer
◦ Hybrids
Packet filtering - Packets (small chunks of data) are
analyzed against a set of filters. Packets that make it
through the filters are sent to the requesting system and all
others are discarded.
Proxy service - Information from the Internet is retrieved
by the firewall and then sent to the requesting system and
vice versa.
Stateful inspection - compares certain key parts of the
packet to a database of trusted information. Information
travelling from inside the firewall to the outside is
monitored for specific defining characteristics, then
incoming information is compared to these characteristics.
If the comparison yields a reasonable match, the
information is allowed through. Otherwise it is discarded.
12. Customizing Firewalls…
Firewall Configuration
Firewalls are customizable. Add or remove filters based on
several conditions. Some of these are:
IP addresses -Based on IP Address
Domain names: Block all access to certain domain names,
or allow access only to specific domain names.
Protocols -Include or exclude protocols in your filters
( TCP, IP, HTTP, FTP, UDP, SMTP, TELNET etc.)
A company might set up only one or two machines to handle
a specific protocol and ban that protocol on all other
machines.
Ports - Any server machine makes its services available to
the Internet using numbered ports, For ex: Web server is
typically available on port 80, and the FTP server is available
on port 21. A company might block port 21 access on all
machines but one inside the company.
13. Specific words and phrases - The firewall
will sniff (search through) each packet of
information for an exact match of the text
listed in the filter. For example, you could
instruct the firewall to block any packet with
the word "X-rated" in it.
With a hardware firewall, the firewall unit
itself is normally the gateway. A good
example is the Linksys Cable/DSL router. It
has a built-in Ethernet card and hub. You
configure the router via a Web-based
interface that you reach through the browser
on your computer. You can then set any filters
or additional information.
14. Firewall technology – Packet
Filtering
Inspecting the "packets”
If a packet matches the packet filter's
set of rules, the packet filter will
◦ drop (silently discard) the packet
◦ reject it
15. Circuit level / Stateful filters
Operates up to layer 4 (transport layer) of the OSI
model.
Examine each data packet as well as its position within
the data stream.
Records all connections passing through it to determine
whether a packet is the start of a new connection, a part
of an existing connection, or not part of any connection.
Though static rules are still used, these rules can now
contain connection state as one of their test criteria.
16. Application layer filtering
Can "understand" certain applications
and protocols (such as File Transfer
Protocol, DNS, or HTTP
Can detect if an unwanted protocol is
sneaking through on a non-standard
port
If a protocol is being abused in any
harmful way.
17. Network Address Translation
(NAT)
Firewalls often have this functionality to
hide the true address of protected hosts.
The hosts protected behind a firewall
commonly have addresses in the "private
address range”.
18. Proxies
A proxy server could be dedicated
hardware or as software on a generalpurpose machine.
Acts as a firewall by responding to
input packets (connection requests,
for example) in the manner of an
application, while blocking other
packets.
19. Hybrid…
Modern firewalls can filter traffic based
on many packet attributes like
source IP address, source port,
destination IP address or port,
destination service like WWW or FTP.
They can filter based on
protocols, TTL values, net block of
originator, of the source, and many
other attributes.
22. What firewalls Accomplish
Prevent access to some web sites!!!
◦ Categories web sites
Adult/Sexually Explicit
Advertisements & Pop-Ups
Chat
Gambling
Games
Hacking
Peer-to-Peer
……
◦ Check by content type
.Exe / .Com
.Mid / .MP3 / .Wav
.Avi / .Mpeg / .Rm
23.
24. Security..
Any system is only as secure as the people
who use it. Education is the best way to
ensure that users take appropriate
precautions:
Install personal firewalls for the client
machines.
Store confidential information in encrypted
form.
Encrypt the stream using the Secure Socket
Layer (SSL) protocol to protect information
flowing between the client and Web sites.
Use appropriate password policies, firewalls,
and routine external security audits.
25. Drawbacks..
Can only protect what goes through the firewall
Host to host authentication and encryption are not
within the ambit of firewalls…
◦ In Essence firewalls only deal with the kinds of connectivity
allowed between different networks – Not with integrity and
privacy of information
Cannot offer protection from trojan type attacks over
IRC( Internet Relay Chat)
No protection from data- driven attacks – malware,
viruses etc.
Overall security architecture must be strong for the
firewall to be effective
E.g. Use USB firewalling technology
No Protection from Ignorance though - Never ever
reveal sensitive information
26. In Summary..
Firewalls help protect your network
from unauthorized access
Provide a single ‘choke point’ or
bottleneck to impose security and
audit
Provide important logging and auditing
functions
27. Tips for enhancing your online
security
Have robust passwords
Never download anything when you
are not sure of the source
Keep your anti virus software updated
Always scan all material before use
Always log out of all your accounts
Never shop online without having you
phishing filter on.
