Some reciprocating open-type compressors used with water cooled systems
incorporate a cylinder head cooling feature in the form of a water circuit
through the compressor head. Supply water enters this before entering the
condenser (see Figure 16).
A rapid indicating thermometer is recommended for taking water temper-
atures because the water regulating valve responds to the operating head
pressure and will vary the temperature of the water as it modulates. It is
also necessary, when adjusting the water regulator, to be able to take inlet and
outlet temperatures quickly.
Critical business systems and their associated technologies are typically held to performance
benchmarks. In the security space, benchmarks of speed, capacity and accuracy are common
for encryption, packet inspection, assessment, alerting and other critical protection technolo-
gies. But how do you set benchmarks for a tool based on collection, normalization and corre-
lation of security events from multiple logging devices? And how do you apply these bench-
marks to today’s diverse network environments? ...

Article 8 of the Charter of Fundamental Rights of the European Union expressly
recognises the fundamental right to the protection of personal data. However, since
the adoption of the Data Protection Directive in 1995, broad technological changes
have taken place1. The ability of organisations to collect, store and process personal
data has increased Not many digital technologies are designed to obtain detailed logs
of their usage by individuals, which are then accessible for surveillance and marketing
Today's complex multi layered security architecture consists of many devices to ensure that servers, hosts,
and applications running on the network are protected from harmful activity. These devices all generate
voluminous logs that are difficult and time-consuming to interpret. In a typical enterprise, an intrusion
detection system can produce more than 500,000 messages per day and firewalls can generate millions of
log records a day.
Lecture 24: The dictionary attack and the rainbow-table attack on password protected systems. The goals of this chapter are: The dictionary attack, thwarting a dictionary attack with log scanning, cracking passwords with direct table lookup, cracking passwords with hash chains, cracking password with rainbow tables.
This second edition of Network security hacks offers 125 concise and practical hacks, including more information for Windows administrators, hacks for wireless networking (such as setting up a captive portal and securing against rogue hotspots), and techniques to ensure privacy and anonymity, including ways to evade network traffic analysis, encrypt email and files, and protect against phishing attacks. System administrators looking for reliable answers will also find concise examples of applied encryption, intrusion detection, logging, trending and incident response.
