Five Things You Hate in a Woman

2008-03-20T16:35:41Z

We use to play E-Spin-the-Bottle in Bloggers-Eg chat room, so Rasha -
E-Nadaha - asked us to write five things we hate to find in a woman.
But, it was really hard to write only five things.

01. Women who want you to care about her, and never show you that she cares about you.

02. Women who has multi-boyfriends, and when you ask her out, or ask
about her phone number, she refuses, webte3mel fiha khadra el sharifa.

03. Woman who is really moody, one day she loves you, and another day she doesn't want to talk to you.

04. Woman who do not trust you, and lies to you.

05. Women who is a real brat, and just want people to love her, while she loves no one.

06. women who tell me that I am kind and polite, for me kind means you are good but not my type.

07. woman who loves me. but when her parents tell her not to marry me, she just listens to them without thinking.

08. woman who is not frank to me, and when she finds something bad in my personality or so, doesn't say it in my face.

09. woman who think that she it is good for her not to call me ever, and I have to call her all the time.

10. woman who is a snitch.

Can you write your own five five things that you hate to find in opposite sex too!?

The Firewall

2008-03-20T16:29:22Z

The Firewall, it's the cornerstone of the Network Security design. In
today's networks, a Firewall is a device that divides the network into
different Segments (Zones), and controls Who's is supposed to talk to
Who, using which Applications (Service), across those different Zones.

Most of the time in enterprise networks, they have two layers of
Firewalls, one at the Gateway - Just behind the Gateway Router - and
the other one in the Data Centre.

The Gateway firewall is also called the Perimeter firewall, its
main task is to control which resources on your local LAN are to be
accessed from the outside world, normally from the Internet. And on the
other direction, it controls what your local users are allowed to do
when going outside, normally to the Internet. The Data Centre firewall
on the other hand is intended to protect the resources in your Data
Centre - mainly Servers - from the outside as well as from the
different Zones in your local network.

Notes:

Sometimes, people who have a tight budget consolidate the Gateway and
the Data Centre firewalls into one firewall. Also this is suitable for
remote branches and small offices.

The computers in the networks world communicate by sending and
receiving packets. These packets contain beside the date (payload), the
source and destinations addresses (IP Addresses) of the sender and
receiver, as well as the service they are using (Protocol and Port
Number). So let's say, if you want to define a rule in your firewall
to let user A in the Users Zone, connect to the Web Server B in the
Data Centre, the rule will contains the address of A in the source IP
field and the Address of B in the Destination IP field, and the Web
Service (Protocol=TCP, Destination-Port=80) in the Service field.

It's really funny that a company like McAfee
claims that they are a Security Vendor, while they do not have
firewalls in their products portfolio. If I were in there shoes, I
would have bought some firewall only company such as Fortinet, Checkpoint, Stonesoft or even a start-up like Palo Alto Networks.

Firewalls Evolution - From Application Aware to UTM

2008-03-20T16:28:35Z

As mentioned earlier,
Firewalls were very successful in segmenting the Network into different
Zones and protecting those different zones from each other by
controlling who is supposed to talk to who using which protocol or
application. But later on, applications such as FTP, SIP, etc. started
to open dynamic ports, and firewalls were forced to evolve and become
more application aware. So firewalls were not limited to Layers Three
and Four (Network and Transport Laters) as they used to be, but they
were able to decode the Application Layer as well.

On the other hand Proxy Firewalls such as Microsoft ISA - I know it�s a
piece of crap - but such firewalls were able to see the application
layer, add rules to prevent people from downloading ZIP and MP3 files,
Inspect SMTP for spam, etc. So firewall vendors were forced to compete
with them in this, especially that such Proxy Firewalls are popular in
SOHO (Small Office and Home Office) and SMB (Small to Medium Business)
networks.

So Firewall vendors decided to focus more on the Application Layer, but
this time it wasn't just an evolution. A new device was introduced to
the market which is UTM.

A Network Layer is a Network Layer, but when it comes to Application
Layer, we have dozens of Applications and each have its own security
requirements. For SMTP, Spam is your enemy. When it comes to File
Sharing, CIFS, FTP, HTTP, SMTP and POP3, you should check the files
being transferred to make sure they do not contain Viruses. IPSs and IDSs
are needed to protect you from the different worms and exploits that
span from layer 2 up to layer 7. So, this is what UTM�s are doing, it�s
a box - mainly a firewall - with many other addons such as Network
Based Antivirus, Network Based Antispam, and Network Based IPS.

Some people may argue
that UTMs are not mature enough and they add complexity to the network.
They also believe that an all-in one solution may not be suitable for
large networks with high throughput. That's why when it comes to ISP's
and large Data Centres they prefer to install separate best-of-breed
devices - Firewall, IPS, AntiSpam - each is responsible for a certain
task. But in some other locations an all in one box (UTM) can reduce
the cost and complexity. Also it's sometimes hard to find a good
stand-alone Network Based Antivirus or Web Filtering Solution and in
such case having those components in a UTM may be your best choice.

Finally, most of the Firewall vendors now are moving towards the
all-in-one solution and I guess in the near future the UTM's will be
mature enough so that stand-alone devices will be something from the
past.

6 Tips to Stop Spywares and Adwares

2008-03-20T16:27:29Z

Every now and then one of my friends or family members tell me that he
has got a Spyware or Adware on his PC, and asks me what to do. There
are many free Antispywares out there, but in fact they never succeeded
in helping those guys. Antivirus vendors are mocking us by claiming
that Viruses and Spywares are two different things, I think they keep
saying so just because their Antivirus softwares are not able to remove
Spywares.

Here you are 6 tips to protect yourself from Spywares, Adwares, etc. In
fact I cannot see any difference between Spyware and Adwares so I'll
call them all from now on Crapwares.

1. Beware of Toolbars et al:

I have to put this number one, Crapwares are always hidden inside
Browser Toolbars, Screen Savers, Games, and MSN Plugins. For the love
of God, please do not install such crap on your PC's. Away from the
Spywares, please tell me what's the point of downloading a freak
toolbar in your browser to make it look ugly and crowded, and what's
the point of installing a plugin in your MSN or Yahoo Messenger to tell
you who has blocked you, let those who block you go to hell.

2. FOSS instead of Free:

We all hate to pay money for Software's. But instead of looking for
Free softwares, search for Open Source ones. Open Source Softwares are
free but their code is published as well for anyone to see it. It's
almost impossible to hide Crapwares in them. Linus Trovalds believes
that Software is like Sex, it's meant to be free. And let me add here,
it's like Sex, you cannot sleep with someone without knowing what she
is hiding under her clothes.

3. A Firewall and a good Antivirus are your Shields:

As I said before, an Antivirus is not the best cure for Crapwares, but
an extra layer of security will not hurt you. And most of the time,
Crapwares need to connect to their mother ship every now and then to
get themselves updated, so a Personal Firewall may not stop them from
infecting you but it will stop them from getting updates and morphing
in Crappier-wares.

4. Beware of malicious sites:

But wait a minute, how can we identify malicious sites? Ok, McAfee
decided to do this for us freely. You can just download their SiteAdvisor Plugin,
and every time you search for something in Google or Yahoo or visit a
certain web site, it will mark safe sites in green and malicious ones
in red.

5. Firefox instead of IE:

Internet Explorer, or sometimes known as Internet Exploder, it the
dominant browser out there, So Crapwares creators and malicious sites
tailor their softwares for it, so why not use a better yet not very
dominant browser such as Firefox or Opera. I know this is somehow Security through Obscurity, but believe me it helps sometimes.

6. Pop-ups are bad:

Sometimes, pop-up windows try to deceive you by making themselves look
like Windows warning messages and claim that you PC is infected or not
healthy. They may ask you to click on a certain link in order to fix
this problem. So, please beware of those evil pop-ups. I know, that
sometimes normal use pop-ups, so it's hard to ask you to totally block
pop-up, but what I normally do here is to block them by default and
allow them only on the sites I trust.
