What is a System Administrator (Sysadmin)?

A system administrator is the person who holds the keys to your company’s digital kingdom. They’re responsible for:

• Acquiring, installing, and configuring critical software and hardware
• Maintaining network and server infrastructure (often 24/7)
• Proactively monitoring systems to prevent downtime
• Troubleshooting problems and coordinating specialists when needed
• Developing and maintaining your company’s IT security plan
• Managing user access, permissions, and administrative privileges

The Fundamental Rule: ONE System Administrator

Policy: assign full administrative privileges to exactly one person.

This doesn’t mean you can’t have IT staff. You can have help desk technicians, network engineers, and specialized support. But full system administrator access—the root/domain admin credentials that can change anything—should belong to one designated individual.

Why Multiple System Administrators Create More Problems Than They Solve

1) Unintentional Conflicts and System Chaos

Two administrators can unknowingly make conflicting changes that cause downtime, misconfigurations, or security gaps:

• Admin A configures firewall rules while Admin B sets different policies
• One installs a patch that conflicts with another’s configuration
• Permissions are modified in parallel, creating access holes
• Critical settings change without communication, triggering outages

2) Documentation Breakdown

Without a strong documentation system (most SMBs don’t have one), multiple admins create silos:

• Changes aren’t consistently logged
• No one has the complete picture of system configuration
• Troubleshooting becomes “Who changed this? When? Why?”
• Knowledge transfer collapses when someone leaves

3) Accountability Disappears

When everyone is responsible, no one is responsible. Multiple admins often leads to:

• Tasks falling through the cracks (“I thought you handled that”)
• No single point of contact during an outage
• Slow resolution and blame-shifting when things go wrong

4) Security Vulnerabilities Multiply

From a cybersecurity perspective, multiple admin accounts increase risk:

• More credentials that can be compromised
• More surface area for phishing and social engineering
• Harder enforcement of MFA and password policies
• Noisy audit trails that make “who did what” unclear

The Right Way to Structure IT Administrative Access

Designate ONE Primary System Administrator

This person is the “change officer.” System-level changes should:

• Be approved by or executed by the primary sysadmin
• Follow a documented change process
• Be logged in your IT documentation system

Give Other IT Staff Limited Administrative Rights

Other staff can have admin rights restricted to their responsibilities:

• Help desk: user creation, password resets, basic access updates
• Network engineer: network device configuration only
• Database admin: database server access only

Principle of least privilege: give people only the permissions they need to do their job—nothing more.

Maintain Executive Access to Admin Credentials

Critical: business owners or executives should have the current admin credentials at all times.

• Store credentials in a secure password manager or safe
• Verify access quarterly (don’t assume it works)
• Update whenever the admin password changes

What Happens When Your System Administrator Leaves Unexpectedly?

This is the nightmare scenario: your sysadmin quits without notice or becomes unavailable. Suddenly you’re locked out, email stops flowing, and business operations stall.
