Password and Credential Management: The Weakest Link in Most Security Systems

Across both cybersecurity and physical access control, an uncomfortable pattern repeats: the most sophisticated systems are routinely undone by the simplest failure — weak, reused, shared, or never-updated credentials. It's rarely the technology that fails; it's the credential discipline around it.
Where this shows up in physical security specifically:
Default credentials left unchanged on camera systems, access control panels, and network equipment installed by a vendor — a documented, common failure across the industry.
Shared access codes or cards among multiple employees, removing any meaningful individual accountability for who actually accessed a restricted area at a given time.
Former employee credentials — physical access cards or system logins — not deactivated promptly after departure, leaving valid access in the hands of someone no longer authorized to have it.
Where this shows up in digital systems:
Reused passwords across multiple systems, meaning a breach of one relatively low-value system can expose credentials that also work on higher-value systems.
No multi-factor authentication on systems where it's available but simply not enabled, leaving a single password as the only barrier to access.
Weak or guessable passwords, particularly common on systems (like camera admin panels) that aren't perceived as high-value targets, even though compromising them can open a path to more sensitive systems.
What good credential management practically requires:
A documented policy covering minimum password standards, rotation where appropriate, and mandatory multi-factor authentication for any system that supports it.
Individual, non-shared credentials for every person and every system — physical access cards included — so access can be tied to a specific individual, not a shared code.
A defined, enforced offboarding process that deactivates all credentials — physical and digital — immediately upon an employee or contractor's departure.
Regular credential audits, checking for default passwords still in use, dormant accounts that should have been deactivated, and shared credentials that should be individualized.
Why this is worth taking seriously despite how basic it sounds. Credential failures aren't sophisticated attacks requiring advanced defenses — they're the digital and physical equivalent of leaving a spare key under the doormat. The fix is almost entirely a matter of discipline and process, not expensive technology, which makes it one of the highest-return, lowest-cost security improvements available to almost any organization.
Durgashtra's integrated security and cybersecurity services include credential management review and hardening as a standard part of any deployment — physical access systems included — because this single area of discipline closes more real-world risk than most far more sophisticated measures.
