In computer security, a Denial-of-Service attack (DoS attack) is an attempt to make a computer resource unavailable to its intended users. Typically the targets are high-profile web servers where the attack is aiming to cause the hosted web pages to be unavailable on the Internet. It is a computer crime that violates the Internet proper use policy as indicated by the Internet Architecture Board (IAB). |

Botnets Exposed: Stopping Next-Generation Attacks |
|
|
The increasing sophistication and dynamism of multi-vectored network attacks, including use of botnets to deliver threats deep inside the enterprise, requires rethinking network security. In light of this sophistication and the corresponding multi-pronged attacks, traditional exploit-based solutions fail to be effective countermeasures to secure the network.

The Security Paradox |
|
|
Medium organizations around the globe are increasingly concerned about cyberthreats, and the rising number of incidents shared publicly certainly justifies their worries. In the first half of 2009, for example, McAfee Labs saw almost as much new malware as it did in all of 2008. At the same time, most organizations have frozen or cut their IT security budgets. Threats up, budgets down. This is what we call the "security paradox."

Why You Should Consider Hosted Messaging Security |
|
|
Hosted, or "in-the-cloud", messaging security capabilities are becoming increasingly
popular with organizations of all sizes. Some have already adopted hosted services, while
others are becoming more receptive to the notion of using third party services to manage
their security infrastructure than they were just a year ago. Particularly driven by the
current economic recession, decision makers are realizing that hosted email security can
provide a cost-effective solution while actually improving security.

Email Encryption for InterScan Messaging Hosted Security |
|
|
Today's confidentiality and privacy requirements drive organizations of all sizes and industries to secure sensitive data in email. Often particular types of data need to be encrypted, such as credit card numbers, intellectual property, or client information. Organizations also need to protect confidential emails for particular groups, such as executive management, human resources or legal departments.
Many organizations are turning to policy-based encryption to meet their encryption needs because it automatically encrypts data using content filtering rules that identify types of content or email for particular groups. Encryption is applied when the rules are triggered. With policy-based encryption, organizations avoid relying on individual users to secure important content.

The Business Benefits of Hosted Email Security for the SMB |
|
|
All businesses face a daily bombardment of email spam that consumes valuable IT staff
time as well as end-user productivity. In addition, email is an attack vector for many
types of security threats to businesses, including phishing, viruses, spyware, and
malicious URLs. Given that all businesses are experiencing the financial pressures of a
tightening world economy, coupled with the uncertainty of any near-term recovery, small
and medium-sized business (SMB) managers are searching for ways to cut costs while
continuing to maintain a consistent level of service and protection for their businesses.

How It Works: InterScan Messaging Hosted Security Advanced |
|
|
According to experts at TrendLabs, spam now makes up close to 95% of all email and continues to grow. In the first three months of 2008 spam rates almost doubled over rates observed at the end of 2007 and TrendLabs predicts that average daily spam volumes will increase by 30 to 50 billion messages per day within the year.1 As spam continues to grow at dramatic rates, traditional on-premise email security products are failing to keep up. This limitation is one of the primary reasons that IDC predicts demand for hosted security solutions -also known as SaaS (Software as a Service) solutions-will grow by more than 30% annually through 2012.2 For context, the growth rate for hosted email security is projected to be more than eight times that of the traditional software email security market, and more than 60% faster than appliance-based email security solutions.

| By : GFI |
Published Date: Jul 24, 2007 |
|
This white paper explains what makes spam such an unbearable problem and how spamming tactics are evolving daily to beat anti-spam software. The latest tactic is to use the common PDF file format to send image spam. By using PDF attachments to send images instead of embedding them in the body of the email message, spammers have taken the cat-and-mouse game with anti-spam software developers to a new level.
