SECURIFY BOLSTERS DEFENSE AGAINST WORMS
Recent Attacks Highlight Need for Top-Down, Policy-Driven Security Methodology
MOUNTAIN VIEW, Calif., September 3, 2003 - Citing the recent
high-profile cyber attacks from MSBlaster, Welchia and other
worms, Securify, Inc., a pioneer and leader in network security
management, today proposed that top-down, policy-driven network
security management, like that provided by Securify SecurVantage™,
is the best defense against current and future worm attacks.
Unlike threat-oriented systems that rely on signature detection
or intrusion prevention techniques to stop attacks in progress,
SecurVantage verifies that the defense infrastructure is responding
appropriately, provides prioritized actions and quantifies
the overall level of risk.
The number of vulnerabilities and exploits is rising exponentially.
According to CERT, more than 76,000 security incidents occurred
in the first two quarters of 2003. That figure represents
a significant increase on an annualized basis from about 82,000
incidents in 2002. Rather than attempt to keep pace with the
rapidly increasing volume of exploits, SecurVantage employs
a customer-specific policy to describe the “correct”
operation of a network, and treats all non-conforming events
as alerts. By monitoring transactions on the network, SecureVantage
presents relevant, actionable and prioritized information
for resolving misconfigurations, removing potential vulnerabilities
and, ultimately, preventing attacks.
“The risk-oriented methodology we have helped customers
deploy starts with visibility into network security and creates
a structured workflow that enables organizations to respond
effectively to events of this nature,” said Taher Elgamal,
chairman and chief technology officer at Securify. “Building
an effective security process, eliminating misconfigurations
and hardening the infrastructure have prepared our customers
to respond effectively based on quantitative information.
Securify has eliminated the infinite rule problem inherent
in traditional threat-oriented tools, relying instead on a
finite rule base of acceptable network behavior defined by
the enterprise.”
With SecurVantage, the issues of false positives, false negatives
and false alarms disappear because any unanticipated network
traffic will trigger an alarm if, and only if, it violates
one or more of the rules in the customer-specific policy.
Further, this approach also detects misconfigurations, by
far the single largest cause of network security problems,
responsible for 65 percent of all network exploits.
Traditional security tools assume all network traffic is acceptable
unless it is explicitly determined to be otherwise. Developed
in the early days of enterprise networks, this approach is
fundamentally flawed because it assumes the impossible burden
of having to know in advance every possible way of exploiting
a network. Methods based on identification of what is "bad,"
are blind to the new attacks appearing virtually daily.
SQL Slammer, Blaster and More to Come
Last January, a Securify customer used a large-scale deployment
of SecurVantage to detect and prevent threats from the SQL
Slammer worm. The worm targeted Microsoft SQL servers, replicating
rapidly and wreaking havoc on poorly defended networks by
vastly increasing traffic loads. Many organizations reported
network and system outages ranging from e-mail disruption
to breakdowns in ATM and emergency response networks.
Because the Securify customer had deployed SecurVantage, they
noticed an abrupt increase in violations generated by the
monitor positioned in their DMZ network. This early warning
occurred well before any internal or external reports of the
attack. The customer was able to confirm that their interior
firewalls and routers were properly blocking the attack and
that no systems were vulnerable within the DMZ. Further, the
customer was able to use information from several other monitors,
deployed at additional geographic locations, to confirm that
the worm was not propagating.
Since then, this customer has successfully employed SecurVantage
to protect their company from all the subsequent worms that
have wreaked havoc on less prepared organizations.
About SecurVantage
Securify SecurVantage consists of Securify SecurVantage Studio,
the policy development and analysis environment; Securify
SecurVantage Monitor, the monitoring and compliance system;
and Securify SecurVantage Enterprise, which aggregates and
analyzes relevant data across an enterprise and presents it
in a variety of reports. Using SecurVantage, enterprises can
specify a formal set of requirements network traffic must
comply with – a "policy" describing the "correct"
behavior of the network – based on corporate security
policy and industry best practices. Using these requirements,
SecurVantage continuously evaluates, in real time, the packets
moving across the network at all levels of the protocol stack,
and makes decisions as to whether or not the traffic is consistent
with the policy. This information is then clearly presented
in a Web-based analysis environment in a format appropriate
to the specific business.
The SecurVantage solution provides detailed information on
all aspects of network security, including network topology;
applications and services for logical network groups; and
asset vulnerabilities. Additionally, trend reports based upon
policy violations can assess specific areas of network operation.
These reports include violation trends by host group; root
cause analysis of recurring events; total traffic and violations
by type of service; device configuration status; access procedure
compliance; service status by host group; and quality of service
for encryption and password strength.
