IT for Halifax law firms: the security and confidentiality baseline

A law firm’s entire product is trust, and most of that trust lives in files: client matters, financial records, privileged communications, identity documents, the details of disputes people would very much prefer stayed private. That is precisely the data attackers want, and precisely the data a firm has a professional duty to protect. For a small Halifax practice without a full-time IT department, the gap between those two facts is where the anxiety lives.

This is a plain-language baseline — the controls a small firm should have in place, why each one matters, and what to check. It is not legal advice, and the specific obligations that govern your practice are for your regulator and your own judgment; treat what follows as the technical floor that supports those obligations rather than a reading of them.

Why firms are targeted

Three reasons, and they compound.

The data is concentrated and valuable. A single matter can contain financial statements, government identification, and confidential negotiations. One firm holds this for hundreds of clients.

Firms move money. Real estate closings and trust accounts make firms a favourite target for wire fraud, where an attacker sits inside an email thread and quietly changes the payment instructions at the last moment.

Security is often thinner than the data warrants. Smaller firms tend to run lean on IT, so the defences do not always match the sensitivity of what is being defended. Attackers know this.

None of that requires a firm to be singled out. Most attacks are opportunistic — a reused password, a convincing email, an unpatched laptop — and the baseline below is aimed squarely at closing those ordinary doors.

The baseline

Multi-factor authentication, everywhere that matters

If you do one thing, do this. Multi-factor authentication means a stolen or guessed password is not enough on its own to get in. Turn it on for email, for your practice management system, for cloud storage, and for banking. Prefer an authenticator app or a hardware key over text-message codes where you can. This single control stops the largest share of account takeovers.

Encryption at rest and in transit

Every firm laptop and phone should have full-disk encryption switched on — BitLocker on Windows, FileVault on Mac — so a device lost in a taxi is a lost asset, not a data breach. Confidential material should travel over encrypted channels, and any portable drive holding client data should be encrypted too. Encryption is cheap, mostly invisible once configured, and turns a stolen device from a reportable incident into an inconvenience.

Backups you have actually tested

Ransomware aimed at a firm does two things: it steals data and it locks you out of your own files. A tested backup answers the second half. You want copies that are recent, that include your practice management data and email, and that an attacker who compromises your network cannot reach or delete — offline or immutable. And you want to have watched one restore, because a backup you have never restored is a hope, not a plan.

Managed, patched devices

Every device that touches client data should be known, kept up to date, and remotely wipeable if it goes missing. Central device management lets you enforce encryption, push security updates, require a screen lock, and remove access from a lost or departed-employee’s machine without chasing it down in person. It is the difference between hoping everyone patched their laptop and knowing they did. This is the ground our device management practice covers.

Email security

Given how much fraud arrives by email, this deserves its own line. Beyond multi-factor on the mailbox, configure your domain’s anti-spoofing records — SPF, DKIM, and DMARC — so it is harder for an attacker to send mail that looks like it came from your firm. Add filtering that catches phishing and dangerous attachments. And build one human habit into the practice: verify any change to payment or wire instructions by a phone call to a known number, never by replying to the email that requested it.

Access control, on a need-to-know basis

Not everyone needs everything. Give each person access to the matters and systems their role requires and no more, so a single compromised account exposes a slice of the firm rather than all of it. Remove access the day someone leaves. Keep administrator accounts separate from everyday logins. This is quiet, unglamorous hygiene, and it dramatically limits the blast radius of any single mistake.

Records retention and disposal

Confidentiality does not end when a matter closes. Decide how long different kinds of records are kept, where, and how they are securely destroyed when that period ends — including the copies sitting in email and on old devices. Holding data forever is not caution; it is a growing pile of risk with no offsetting benefit. Your retention obligations are a matter for your regulator and your own policies, but the technical requirement is simple: know where the data is so you can both protect it and dispose of it deliberately.

Putting it in order

If this list feels like a lot, sequence it by payoff:

1. Multi-factor authentication on email and the systems holding client data — the highest return for the least effort.
2. Encryption on every device, verified rather than assumed.
3. A tested backup with at least one offline or immutable copy.
4. Managed devices, so the first three stay true as staff and hardware change.
5. Email anti-spoofing and a wire-verification habit, aimed at the fraud firms actually face.
6. Access reviews and a retention policy, revisited on a schedule.

None of these are exotic, and none require an in-house IT team to maintain. What they require is that someone owns them and checks them, rather than assuming they were handled once and stayed handled.
