Just because the recession has left you penniless doesn't mean you can't keep your computer safe: Here are a dozen security apps that don't cost a thing.
| on Yahoo! |
Today more than ever, you need to protect your computer systems against intrusion by spyware, viruses, Trojans, and the like. Malware is big business now. Programmers for the Dark Side write tight, tested, evil code for pay, and their bosses rake in money by capturing passwords, stealing credit card numbers, and duping the gullible. Now there's a business sector that's booming! Fortunately you can protect yourself without shelling out a penny. It's true that paid solutions like Prevx 3.0, Spyware Doctor with AntiVirus 6, and Webroot AntiVirus with AntiSpyware 6.1 score better than the freebies in testing, but you can improve your defenses by layering multiple free products.
Yes, I always advise against running more than one real-time anti-malware product, since there can be conflicts. In particular, I wouldn't use avast! antivirus 4.8 Home Edition and AVG Anti-Virus Free 8.0 together, since they are both traditional signature-based products with real-time protection. But the free edition of MalwareBytes' Anti-Malware 1.36 is a scan-only product with no real-time protection, which makes it safer as a companion product for either.
Adding behavior-based protection to your traditional signature-based protection naturally increases your coverage. The behavior-based zero-day threat protection in ThreatFire 4.5 is specifically designed to work alongside signature-based products. Panda Cloud Antivirus also includes behavioral detection, and it keeps its intelligence in the cloud, not on your PC. It's not as fast or powerful as Prevx, another in-the-cloud product, but it's a free, lightweight addition.
Free Spam Filtering
Wouldn't you like some good news for a change? Want free money from a long-lost relative in Nigeria? Hope to win a European lottery that you didn't even enter? Just check your e-mail! Spammers may well have filled it with messages of hope…false hope, that is. Spam about V!agra and Ci@lis is down; spam about money is up—not surprising these days. And, hey, if "your bank" sends an e-mail about some dire account problem that will send you to the poorhouse, don't click any links. Navigate directly to the bank site yourself. Of course, a decent antispam app could fix that problem, too.
Maybe you're one of the lucky ones whose ISP or Web-based e-mail provider includes server-level spam filtering as part of the service. But if spam is reaching your inbox you can rely on the free SPAMfighter Standard to keep it out. Like the highly successful commercial products Cloudmark Desktop and iHateSpam, SPAMfighter is a community-based filter. That means it will let through a small amount of spam (less than most other antispam products), but it will never throw a valid personal message into the spam bin. It inserts a small advertising footer in your outgoing messages, but that's a small price to pay.
Free Firewall
When old-timers fell on hard times, they'd describe their plight by moaning, "The wolf is at the door!" These days we might say, "The hacker is at the port." If you don't have some kind of firewall protection, a hacker or network-based worm could waltz right in through an open port and take control of your computer. Certainly, if you have no other protection, you should make sure the Windows Firewall in XP or Vista is turned on.
Free third-party personal firewalls ZoneAlarm 8.0 and Comodo Firewall Pro 3.0 do more than the built-in, though. Naturally they block hack attacks, masking your computer's ports so they're completely invisible from the outside. But they also protect against betrayal from within by limiting which programs are allowed to connect with the Internet. Initially they can be noisy, popping up a flood of queries asking whether this or that program should be allowed access. After a while, the pop-ups diminish. Comodo does automatically configure access for many programs, which may cut down on pop-ups. ZoneAlarm reserves automatic configuration for its paid versions.—Next: Free Parental Control and More >
Anti-Malware
avast! antivirus 4.8 Home Edition
Its virus protection isn't far behind that of the top antivirus products. It removes spyware nearly as well as the top antispyware, and its resident protection against new infestation is excellent. This is some seriously impressive protection, considering that it's free for personal use.
AVG Anti-Virus Free 8.0AVG Anti-Virus Free 8.0's protection is nearly as good as that of the top for-pay antivirus and antispyware products. Scanning of search links for dangerous pages is an added bonus. And as long as it's for your personal home use, it's free!
Malwarebytes' Anti-Malware 1.36
Malwarebytes' Anti-Malware does a good job of cleaning up malware, especially those annoying rogue security programs, though it's not effective against commercial keyloggers or rootkits. And the real-time protection in the extra-cost Pro edition isn't worth the money. But be sure to add the free edition to your security arsenal.
Panda Cloud Antivirus 0.9 Beta
This lightweight, attractive, free anti-malware tool uses no signatures. All malware detection occurs online. Some snags I hit in testing indicate that Panda still has a little work to do on this beta. But even now it's effective at protecting a clean system.
ThreatFire 4.5Your standard signature-based anti-malware utility catches most things that attack your computer. ThreatFire offers supplemental protection against zero-day attacks that are too new to have a signature. It's a fine, free addition to your security arsenal—I use it myself.
Antispam
SPAMfighter StandardIf you need free spam filtering and don't mind having an advertising footer added to all your outgoing messages, this is a great solution. It's nearly as effective as the best community-based filters. If you need the features of the $29 Pro edition, though, I'd suggest looking at iHateSpam ($19.95) or Cloudmark Desktop ($39.95) instead.
Firewall
Comodo Firewall Pro 3.0
Comodo Firewall Pro 3.0 aces all the basic personal firewall tasks. Its Defense+ module protects critical system areas. Yes, Defense+ flags both good and bad programs, but Installation mode can cut down the hassle factor. Best of all, it's totally free for personal or professional use.
ZoneAlarm 8.0ZoneAlarm 8.0 offers effective basic personal firewall protection at a fantastic price—free! But if you want advanced features like automatic program control configuration, exploit prevention, or behavior-based operating-system protection, you'll have to upgrade to the paid version.
Parental
K9 Web Protection 4.0This parental-control utility lacks many features found in the competition, most notably the ability to define different settings for different users. But what it does, it does well. If you can live within its limitations it's a good, free choice.
OnlineFamily.NortonThis free Web-based product has everything you'd expect in a parental-control system, and more. It blocks bad sites, controls time on the computer, supervises chat, and even watches social network use on all your PCs and Macs. Settings are stored in the cloud, making remote configuration and reporting simple.
Password Management
LastPass 1.50
LastPass is a free, feature-rich password manager and Web form filler. It has almost every software feature found in any competitor, plus some unique features of its own. Numerous mobility options mean you can use it wherever you are.
Utility
AppRemover 1.5
AppRemover aims to clean up traces of old security products that keep you from installing a new one. It doesn't support uninstallation of every product and doesn't successfully clean out all those it does support. Still, give it a try if you're vexed by "stuck" security. It's free, it's lightweight, and it couldn't hurt.

[edit] Types of security
[edit] Network layer security
TCP/IP can be made secure with the help of cryptographic methods and protocols that have been developed for securing communications on the Internet. These protocols include SSL and TLS for web traffic, PGP for email, and IPsec for the network layer security.[edit] IPsec Protocol
This protocol is designed to protect communication in a secure manner using TCP/IP. This is a set of security extensions developed by IETF and it provides security and authentication at the IP layer by using cryptography. To protect the content, the data is transformed using encryption techniques. There are two main types of transformation that form the basis of IPsec: the Authentication Header (AH) and Encapsulating Security Payload (ESP). These two protocols provide data integrity, data origin authentication, and anti-reply service. These protocols can be used alone or in combination to provide desired set of security services for the Internet Protocol (IP) layer.The basic components of the IPsec security architecture are described in terms of the following functionalities:
- Security protocols for AH and ESP
- Security association for policy management and traffic processing
- Manual and automatic key management for the internet key exchange (IKE)
- Algorithms for authentication and encryption
[edit] Electronic mail security (E-mail)
[edit] Background
See also: Electronic mail
Email messages are composed, delivered, and stored is helpful in a multiple step process, which starts with the message's composition. When the user finishes composing the message and sends it, the message is transformed into a standard format: an RFC 2822 formatted message. Afterwards, the message can be transmitted. Using a network connection, the mail client, referred to as a mail user agent (MUA), connects to a mail transfer agent (MTA) operating on the mail server; the mail client then provides the sender’s identity to the server. Next, using the mail server commands, the client sends the recipient list to the mail server; the client then supplies the message. Once the mail server receives and processes the message, several events occur: recipient server identification, connection establishment, and message transmission. Using Domain Name System (DNS) services, the sender’s mail server determines the mail server(s) for the recipient(s). Then, the server opens up a connection(s) to the recipient mail server(s) and sends the message employing a process similar to that used by the originating client, delivering the message to the recipient(s).[edit] Pretty Good Privacy (PGP)
PGP provides confidentiality by encrypting messages to be transmitted or data files to be stored using an encryption algorithm such 3DES or CAST-128. Email messages can be protected by using cryptography in various ways, such as the following:- Signing an email message to ensure its integrity and confirm the identity of its sender.
- Encrypting the body of an email message to ensure its confidentiality.
- Encrypting the communications between mail servers to protect the confidentiality of both the message body and message header.
[edit] Multipurpose Internet Mail Extensions (MIME)
MIME transforms non-ASCII data at the sender's site to Network Virtual Terminal (NVT) ASCII data and delivers it to client's Simple Mail Transfer Protocol (SMTP) to be sent through the internet.[4] The server SMTP at the receiver's side receives the NVT ASCII data and delivers it to MIME to be transformed back to the original non-ASCII data.- Secure/Multipurpose Internet Mail Extensions (S/MIME)
[edit] Firewalls
A firewall controls access between networks. It generally consists of gateways and filters which vary from one firewall to another. Firewalls also screen network traffic and are able to block traffic that is dangerous. Firewalls act as the intermediate server between SMTP and HTTP connections.[edit] Role of Firewalls in Internet Security
Firewalls impose restrictions on incoming and outgoing packets to and from private networks. All the traffic, whether incoming or outgoing, must pass through the firewall; only authorized traffic is allowed to pass through it. Firewalls create checkpoints between an internal private network and the public Internet, also known as choke points. Firewalls can create choke points based on IP source and TCP port number. They can also serve as the platform for IPsec. Using tunnel mode capability, firewall can be used to implement VPNs. Firewalls can also limit network exposure by hiding the internal network system and information from the public Internet.[edit] Types of firewalls
[edit] Packet Filters
Packet filters are one of several different types of firewalls that process network traffic on packet-by-packet basis. Their main job is to filter traffic from a remote IP host, so a router is needed to connect the internal network to the internet. The router is known as a screening router, which screens packets leaving and entering the network.[edit] Circuit-Level Gateways
The Circuit-Level Gateway is a proxy server that statically defines what traffic will be allowed. Circuit proxies always forward packets containing a given port number, provided the port number is permitted by the rules set. This gateway operates at the network level of an OSI model. The main advantage of proxy server is its ability to provide Network Address Translation (NAT), which can hide the user's IP address from the Internet, effectively protecting all internal information from the Internet.[edit] Application-Level Gateways
An application-level gateway is a proxy server operating at the TCP/IP application level. A packet is forwarded only if a connection is established using a known protocol. Application-level gateways are notable for analyzing entire messages rather than individual packets of data when the data are being sent or received.[edit] Malicious software and antivirus
[edit] Malware
For more details on this topic, see Malware.
Commonly, a computer user can be tricked or forced into downloading software onto a computer that is of malicious intent. Such programs are known as malware and come in many forms, such as viruses, Trojan horses, spyware, and worms. Malicious software is sometimes used to form botnets.[edit] Viruses
For more details on this topic, see Computer virus.
Viruses are programs that can replicate their structures or effects by infecting other files or structures on a computer. The common use of a virus is to take over a computer to steal data.[edit] Trojan horse
For more details on this topic, see Trojan horse.
A Trojan horse (commonly known as a Trojan) is a general term for malicious software that pretends to be harmless so that a user willingly allows it to be downloaded onto the computer.[edit] Spyware
For more details on this topic, see Spyware.
The term spyware referrs to programs that surreptitiously monitor activity on a computer system and report that information to others without the user's consent.[edit] Worms
For more details on this topic, see Worms.
Worms are programs that can replicate themselves thoughout a computer network, performing malicious tasks throughout.[edit] Botnet
For more details on this topic, see Botnet.
A botnet is a network of "zombie" computers that have been taken over by a "bot" that performs large-scale malicious acts for the creator of the botnet.[edit] Antivirus
For more details on this topic, see Antivirus.
Antivirus programs and Internet security programs are useful in protecting a computer or programmable device from malware.Such programs are used to detect and usually eliminate viruses; however, it is now common to see security suites, containing also firewalls, anti-spyware, theft protection, and so on to more thoroughly protect users [6].
Traditionally, a user would pay for antivirus software; however, computer users now can, and do, download from a host of free security applications on the Internet.[7]
