问题     Smart firms can  minimize their risks by conducting weakness appraisals, choosing experienced security personnel and establishing-and then enforcing-robust security policies and procedures.
    First, recruit responsible, experienced network administrators consultants and in-house security officers, experts’ advice. Run background checks on any individuals who will be given privileged access to your company’s computer system, lf your firm lacks the resources to properly monitor security around-the-clock, consider giving the job to a qualified security company.
    Security personnel should conduct regular tests to search for weakness and stay informed of software upgrades and updates, especially for popular programs such as Microsoft Office. Remember, hackers read security bulletins and manufacturer releases shout program flaws, too.
    Finns with slack security are easy prey for what experts call "social engineering" crimes, the oldest form of hacker attacks. In these schemes, individuals assume false identifies (as utility workers, telephone repairers, messengers, or computer technicians) to deceive employees into disclosing their passwords and other information. Some hackers even take temporary positions on night cleaning crews so they can browse files, poke through trash or install devices to extract information.
    To combat such break-ins, instruct employees to report unfamiliar visitors and refrain from typing their password and other confidential data when others are nearby. Company telephone and communications closets should remain locked at all times, too.
    Employees also should be told to fever reveal passwords (even when asked by a network administrator). Other reckless behavior to be avoided includes keeping "password reminders" on monitors, tacked to cork boards, or trader keyboards Under no circumstances should employees select easy-to-guess passwords such as their nickname or the name of their child, spouse, pet or car
    Whenever possible, encourage employees to create seven-character passwords consisting of small and capital letters, numbers and symbols. Such passwords prove tough for hackers; they can take months to crack. Conversely, short four-letter passwords, composed entirely of small letters, are straightforward to crack and can be deduced in only a few minutes. Hackers sometimes employ "dictionary attacks"--running programs that lay every word in the dictionary--to crack passwords.
    One solution to password management problems is what’s called "two-factor access." Employees are given security tokens that display regularly changing information that must be typed during log-in. The employees then type their own password to further verify their identity.
The expression "around-the-clock" (Line 4, Para. 2) most probably means______.
